Eligibility criteria:

        Inclusion Criteria:

        Patients are included in the study if all of the following criteria are met:

          -  The patient speaks and writes in English.

          -  The patient is a man or woman of any ethnic origin aged 18 through 65 years.

          -  The patient is in good health as determined by a medical and psychiatric history,
             medical examination, serum chemistry, and hematology.

          -  The patient has a diagnosis of SWSD according to the International Classification of
             Sleep Disorders (ICSD) criteria, and must have had excessive sleepiness during night
             shifts for at least 3 months.

          -  The patient must be planning to work at least 3 to 5 nights (per week), of which at
             least 3 nights will be consecutive.

          -  The patient must work night shifts that include at least 6 hours between 2200 and 0800
             (+30 minutes) and be no longer than 12 hours (+30 minutes) in duration.

          -  The patient has a mean sleep latency of 6 minutes or less as determined by the MSLT
             (average of naps at 0100, 0300, 0500, and 0700).

          -  The patient has a Clinical Global Impression of Severity of Illness (CGI-S) rating of
             4 or more as it pertains to sleepiness during night shifts including the commute from
             work.

          -  Women of childbearing potential (not surgically sterile or 2 years postmenopausal)
             must use a medically accepted method of contraception and must agree to continue use
             of this method for the duration of the study and for 30 days after participation in
             the study. Acceptable methods of contraception include abstinence, barrier method with
             spermicide, steroidal contraceptive (oral, transdermal, implanted and injected) in
             conjunction with a barrier method, and intrauterine device (IUD).

          -  The patient is willing to comply with study restrictions and remain at the clinic
             overnight as required.

          -  The patient may have been prescribed PROVIGIL or stimulant therapy for their sleep
             disorder; however, they must have undergone a washout period of at least 7 days prior
             to screening assessments done at the second screening visit.

        Exclusion Criteria:

        criteria are met:

          -  The patient consumes caffeine including coffee, tea, and/or other caffeine-containing
             beverages or foods averaging more than 600 mg of caffeine/day within 2 weeks of the

             screening visit.

          -  The patient has clinically significant deviation from normal in clinical laboratory
             results, vital signs, or physical examination.

          -  The patient has received any investigational drug within 30 days or 5 half-lives
             (whichever is longer) before study drug administration, or in the case of a new

             adminstration.

          -  The patient used any prescription drugs disallowed by the protocol or clinical
             significant use of over-the-counter (OTC) drugs within 7 days before the second
             screening/baseline visit.

          -  The patient has any disorder (including gastrointestinal surgery) that may interfere
