NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

In the opinion of management, the accompanying unaudited condensed
consolidated financial statements include all adjustments, consisting only of normal, recurring accruals, necessary for their fair
presentation in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). Preparing
financial statements requires management to make estimates and assumptions that affect the reported amounts of assets,
liabilities, revenue, and expenses. Actual results and outcomes may differ from managements estimates and assumptions.

The information included in this Form 10-Q should be read in conjunction with
Managements Discussion and Analysis and consolidated financial statements and notes thereto included in the Companys
Annual Report on Form 10-K for the year ended March 31, 2005.

Note 1  Accounting Principles
The accounting principles followed in the preparation of the financial information contained herein are the same as those
described in the Companys Annual Report on Form 10-K for the year ended March 31, 2005. Refer to the Annual Report on Form
10-K for detailed information on accounting policies.

Note 2  Stock-Based Compensation
The Company accounts for stock-based compensation arrangements in accordance with the provisions of Accounting Principles
Board Opinion (APB) No. 25, Accounting for Stock Issued to Employees, and complies with the disclosure
provisions of SFAS No. 123, Accounting for Stock-Based Compensation as amended by SFAS No. 148, Accounting for
Stock-Based Compensation. Under APB No. 25, compensation cost is determined based on the difference, if any, on the grant
date between the fair value of the Companys stock and the amount an employee must pay to acquire the stock. Accordingly, no
compensation expense associated with the intrinsic value of stock option grants or shares sold to employees under the Employee
Stock Purchase Plan has been recognized in the Companys financial statements.

Note 3  Marketable Securities
The Company classifies its marketable debt securities as available-for-sale and records these securities at fair market value.
Net realized and unrealized gains and losses are determined on the specific identification cost basis. Any unrealized gains and
losses, net of deferred income taxes, are included in stockholders equity as a separate component of other comprehensive
income. A decline in the market value of any available-for-sale security below cost that is deemed other than temporary, results
in a charge to operations and the establishment of a new cost basis for the security. Realized securities gains or losses are
included in investment income in the consolidated statements of operations.

For the three months ended December 31, 2005 and 2004 there were 7,000 and
1,000 options, respectively, that were excluded in the calculation of potential common shares because the exercise price of the
options were higher than the average market price for the three month period. For the nine months ended December 31, 2005 and 2004
there were 7,000 and 322,320 options, respectively, that were excluded in the calculation of potential common shares because the
exercise price of the options were higher than the average market price for the nine month period.

Note 8  Dividends
The Company declared a $.06 per share cash dividend on October 25, 2005 for shareholders of record as of November 18, 2005 and
paid on December 2, 2005. Total amount of dividends paid on December 2, 2005 was $853,000. Total dividends paid for the nine
months ended December 31, 2005 were $2,558,000. The Company paid dividends of $2,086,000 during the nine months ended December 31,
2004.

Note 9  Income Taxes
As part of the process of preparing financial statements, the Company is required to estimate income taxes, both state and
federal. This process involves management estimating the actual current tax exposure together with assessing temporary differences
resulting from different treatment for tax and accounting purposes. These differences result in deferred tax assets and
liabilities, which are included within the consolidated balance sheet. Management must then assess the likelihood that deferred
tax assets will be utilized to offset future taxable income during the periods in which these temporary differences are
deductible. Management believes that as of December 31, 2005, based on the level of historical taxable income and projections of
future taxable income for the periods in which the deferred tax assets are deductible, it is more likely than not that the Company
will realize the benefits of these deductible differences.

Note 10  Subsequent Event
On January 4, 2006, the Company purchased a portfolio of domestic and international patents and patents pending related to the
FiberChoice brand for approximately $8.0 million in cash from Onesta Nutrition, Inc.

Managements Discussion and Analysis of Financial Condition and Results
of Operations may contain statements that are forward-looking. These statements are based on current expectations and assumptions
that are subject to risks and uncertainties. Actual results could differ materially because of factors discussed under

This Quarterly Report on Form 10-Q should be read in conjunction with the
Companys Annual Report on Form 10-K for the year ended March 31, 2005.

Overview
We are in the business of developing and marketing consumer health care products, including Breathe Right® branded
products focused on better breathing, and FiberChoice® branded products focused on digestive health. We operate in niche
categories of the large over-the-counter health care market with unique product offerings that are supported by strong advertising
and promotion programs. Our competitive strengths include our brands and patented technologies, well-established distribution
networks domestically and internationally, a flexible and low-cost operating model and an experienced management team.

Our principal product, the Breathe Right nasal strip, improves breathing by
dilating the nasal passages. Nasal strips provide temporary relief from nasal congestion and stuffiness resulting from a variety
of health conditions, and also reduce or eliminate snoring. Breathe Right nasal strips, and the entire Breathe Right product line,
provide consumers drug free better breathing solutions. Breathe Right nasal strips are sold in the United States and
26 markets internationally.

The Breathe Right brand has been further extended by the launch of new
products such as Breathe Right Snore Relief throat spray in fiscal 2003 and the launch of Breathe Right Vapor Shot! personal
vaporizer in fiscal 2004.

We entered the bulk fiber category in March 2000 with the launch of the
FiberChoice brand. The original FiberChoice product is an orange flavored chewable fiber tablet that offers consumers an
effective, convenient and good-tasting way to supplement their daily intake of dietary fiber. In March 2005, CNS extended the
FiberChoice line to include sugar-free chewable fiber tablets in assorted fruit flavors and a low-sugar, hard candy fiber drop. We
recently announced the introduction of two additional product offerings under the FiberChoice brand, FiberChoice plus
Calcium and FiberChoice Weight Management. These two new products will begin shipping to retailers in February 2006.

In addition to further organic development and expansion of the Breathe Right
and FiberChoice brands, we are exploring opportunities to acquire established consumer health care brands, product lines and new
technologies that complement our better breathing and digestive health platforms.

For the quarter ended December 31, 2005, net sales were $30.9 million, an
increase of 7.6% versus net sales of $28.7 million for the quarter ended December 31, 2004. For the nine month period ended
December 31, 2005, net sales increased by 23.3% to $80.5 million compared to net sales of $65.3 million for the nine month period
ended December 31, 2004.

Domestic net sales for the quarter ended December 31, 2005 of $25.6 million
increased by 3.3% compared to the quarter ended December 31, 2004. For the quarter ended December 31, 2005, net sales of domestic
Breathe Right brand products decreased by 1.4% compared to the strong results for the quarter ended December 31, 2004 relating to
increased consumer demand associated with the re-launch of the clear nasal strip and less effective advertising and promotions
during the third quarter of fiscal 2006. Net sales of FiberChoice brand products were $4.1 million for the quarter ended December
31, 2005, an increase of 38.4% compared to the quarter ended December 31, 2004. FiberChoice sales growth resulted from continued
improvement in consumer demand for the expanded offerings of FiberChoice products. For the two FiberChoice products launched in
the March 2005 quarter, the assorted fruit flavored tablet has exceeded internal expectations and is currently the fastest-selling
product in the FiberChoice product line, while the hard candy fiber drop has fallen short of internal expectations. FiberChoice
also benefited from the expansion of advertising coverage to 100% of the United States compared to 85% of the United States in the
prior year period.

For the nine months ended December 31, 2005, net sales of domestic Breathe
Right branded products increased by 11.8%, to $54.7 million and FiberChoice branded products grew by 68.8%, to $13.8 million
compared to the nine months ended December 31, 2004.

Breathe Right international net sales for the quarter ended December 31, 2005
increased by 34.8% to $5.3 million compared to $3.9 million for the quarter ended December 31, 2004. The increase in international
net sales for the three months ended December 31, 2005 is the result of continued strong sales to Canada as well as normal
shipments to Japan. During the first eight months of fiscal 2005, no revenues were recorded to Japan due to high inventory levels
in that market. For the nine months ended December 31, 2005, Breathe Right international net sales increased by 48.3% over the
prior year period to $11.9 million.

We believe the percentage relationship between net sales and major expense
lines in the statement of operations and the percentage change in the dollar amounts of each of the items presented below is
important in evaluating the performance of our business operations.

Gross profit as a percentage of sales decreased from 75.3% in the quarter
ending December 31, 2004 to 69.6% in the current quarter ending December 31, 2005. The decrease in gross profit rate was the
result of a $1.1 million benefit relating to a European import duty refund recognized during the quarter ended December 31, 2004,
as well as current quarter changes in product mix and an additional provision for obsolete inventory. Gross profit as a percentage
of sales for the nine months ended December 31, 2005 decreased to 70.2% compared to the prior year gross margin percentage of
72.1% due primarily to the prior year benefit of the European import duty refund.

Advertising and promotion expense for the quarter ended December 31, 2005 was
$11.4 million compared to $10.7 million for the same period of 2004, an increase of 6.4%. The increase in advertising and
promotion expense is the result of increased levels of Breathe Right International and FiberChoice advertising. Overall,
advertising and promotion expense as a percent of sales decreased slightly to 36.9% for the quarter ended December 31, 2005
compared to 37.3 % for the same quarter of the prior year. For the nine months ended December 31, 2005, advertising and promotion
expense as a percent of sales decreased by 1.9 percentage points compared to the same period of the prior year, reflecting
economies of scale related to the Breathe Right domestic advertising and promotional programs.

Selling, general and administrative expenses decreased to $4.2 million for
the quarter ended December 31, 2005 compared to $4.5 million for the same quarter of 2004. The expense decrease reflects lower
legal fees relating to regulatory compliance and defense of the Companys intellectual property, as well as lower
compensation expense. Selling, general and administrative expense as a percent of net sales decreased from 15.7% for the quarter
ended December 31, 2004 to 13.6% for the quarter ended December 31, 2005 and from 17.8% for the nine months ended December 31,
2004 to 16.1% for the nine months ended December 31, 2005. The improvements in selling, general and administrative expense as a
percentage of net sales result from lower levels of legal expense and leveraging of fixed corporate overhead expense.

Operating income for the quarter ended December 31, 2005 declined from 22.3%
of net sales for the three months ended December 31, 2004 to 19.1% of sales for the three months ended December 31, 2005. The
decline in operating profit margin for the three months ended December 31, 2005 resulted from the lower gross margin rate, as
described above, partially offset by lower operating expenses as a percentage of sales. For the nine months ended December 31,
2005, operating profit margin improved to 23.0% of net sales compared to 21.4% for the nine months ended December 31, 2004, with
the lower gross profit rates being more than offset by lower operating expenses as a percentage of sales.

Investment income was $330,000 for the quarter ended December 31, 2005
compared to $256,000 for the same quarter of 2004. The increase in market interest rates compared to the prior year quarter
produced the increase in investment income. The Company has invested substantially all of its marketable securities in tax-exempt
investments that provide higher after-tax returns.

Net income for the three months ended December 31, 2005 declined by 9.9% to
$4.0 million, compared to $4.4 million in the three months ended December 31, 2004. The decline results from the prior year after
tax benefit of the European import duty refund of $662,000 and the impact of a slightly higher effective tax rate partially offset
by an 8.0% revenue growth for the quarter and leveraging of operating expenses. Net income for the nine months ended December 31,
2005 increased 31.2% to $12.5 million compared to $9.6 million for the nine months ended December 31, 2004 driven by 23.3% growth
in revenue and leveraging of operating expense, partially offset by the prior year benefit of the European import duty refund and
a slightly higher effective tax rate.

Our financial position continues to be strong, with cash and marketable
securities of $59.7 million and no debt as of December 31, 2005.

Seasonality
The Company has experienced in the past, and expects that it will continue to experience in the future, quarterly fluctuations
in both domestic and international sales and earnings. These fluctuations are due in part to advertising levels and seasonality of
sales, as well as increases and decreases in purchases by distributors and retailers in anticipation of future demand by
consumers. The Company believes that significant portions of the Breathe Right® product line are used for the temporary relief
of nasal congestion and congestion-related snoring. Sales of nasal congestion remedies are higher during the fall and winter
seasons, corresponding with the Companys third and fourth quarters.

Liquidity and Capital Resources
As of December 31, 2005, we had cash and marketable securities of $59.7 million and no debt on our balance sheet. The existing
cash and marketable securities may be used to acquire complementary consumer healthcare businesses or technologies, fund internal
development of new products and expansion of existing product lines, pay dividends to our shareholders and/or buy back additional
shares of CNS common stock.

Cash generated from operating activities for the nine months ended December
31, 2005 was $9.6 million, compared to $11.2 million in the prior year period. The decrease in cash generated from operations was
driven by increases in accounts receivable, inventories and prepaid expenses reflecting seasonality of the business and increased
new product launches and marketing activity compared to the prior year. These uses of cash from operating activities were
partially offset by growth in net income and an increase in accounts payable.

Sales and maturities of marketable securities exceeded purchases by $3.0
million for the nine months ended December 31, 2005.

There were 358,535 shares of common stock issued for $1.7 million during the
nine months ended December 31, 2005 under our Employee Stock Purchase Plan and shareholder approved equity compensation plans.

The Company repurchased 435,105 shares of common stock for $9.2 million
during the nine months ended December 31, 2005 at an average price of $21.24 per share. On August 2, 2005, the board of directors
authorized the repurchase of up to 1,000,000 additional shares of the Companys common stock under the CNS stock repurchase
program. At December 31, 2005, there remains authority to repurchase up to 990,400 additional shares of our common stock in
connection with the stock repurchase program.

The board of directors declared a $.06 per share cash dividend on October 25,
2005 for shareholders of record as of November 18, 2005. The amount of this dividend payment, paid on December 2, 2005, was
$852,000. Dividends of $697,000 were paid during the three months ended December 31, 2004. The Company paid dividends of $2.6
million and $2.1 million for the nine months ended December 31, 2005 and 2004, respectively.

On January 4, 2006, the Company purchased a portfolio of domestic and
international patents and patents pending related to the FiberChoice brand for approximately $8.0 million in cash from Onesta
Nutrition, Inc.

We believe that our existing funds and funds generated from operations will
be sufficient to support our planned operations for the foreseeable future.

Forward-Looking Statements

Certain statements contained in this Report on Form 10-Q and other written
and oral statements made from time to time by the Company do not relate strictly to historical or current facts but provide
current expectations or forecasts of future events. As such, they are considered forward-looking statements under the
Private Securities Litigation Reform Act of 1995 and are subject to certain risks and uncertainties that could cause actual
results to differ materially from those presently anticipated or projected. Such forward-looking statements can be identified by
the use of terminology such as may, will, expect, plan, intend,
anticipate, estimate, or continue or similar words or expressions. It is not possible to
foresee or identify all factors affecting the Companys forward-looking statements and investors therefore should not
consider any list of factors to be an exhaustive statement of all risks, uncertainties or potentially inaccurate assumptions.
Factors that could cause actual results to differ from the results discussed in the forward-looking statements include, but are
not limited to, the following factors: (i) the Company depends on sales of Breathe Right nasal strips for the majority of its
revenue; (ii) the Companys business is subject to seasonality, with sales typically higher in the fiscal third and fourth
quarters of each year due to the cold/flu season and its revenues and earnings may be impacted by the relative severity of such
season; (iii) the Companys success and future growth will depend significantly on its ability to develop and achieve markets
for additional products; (iv) the Companys competitive position will, to some extent, be dependent on the enforceability and
comprehensiveness of the patents on its Breathe Right nasal strip technology which have been, and in the future may be, the
subject of litigation and could be narrowed as a result of the outcome of the reexamination of one such patent by the United
States Patent and Trademark Office; (v) the Company has faced and will continue to face competition in its market; (vi) the
Company relies on third-party manufacturers for the production of all of its products; and (vii) the Company relies on a single
third-party manufacturer for the production of its Breathe Right nasal strip products, with the raw materials being supplied by a
sole source and other factors and risks, including those set forth in the Companys reports filed with the Securities and
Exchange Commission, including those risks identified in the section entitled Risk Factors in the Companys
Annual Report on Form 10-K for the year ended March 31, 2005. These forward-looking statements are made as of the date of this
report and the Company assumes no obligation to update such forward-looking statements, or to update the reasons why actual
results could differ materially from those anticipated in such forward-looking statements.

Item 3.   Quantitative and QualitativeDisclosures about Market Risk

The Companys market risk exposure is primarily interest rate risk
related to its cash, cash equivalents and investments in marketable securities. The Companys risk to interest rate
fluctuations has not materially changed since March 31, 2005. See Item 7A of the Companys Annual Report on Form 10-K for the
