Update:  Great side effect: No more snoring!
Update to my review from 2009:<br />I have found the same product for much cheaper at my local Costco: a bottle of Kirkland "Mucus Relief Chest Guaifenesin 400 mg, 200 tablets" for $11.55 ($0.06/400 mg tablet) instead of this ProHealth product of 100 tablets for ~$20 ($0.20/400 mg tablet). The ProHealth is over 3 times the price!  And the Kirkland brand tablets are MUCH easier to swallow.<br /><br />The price at my local Costco is currently cheaper, btw, than buying the same Kirkland bottle on amazon (http://www.amazon.com/Kirkland-Signature-Expectorant-Guaifenesin-Immediate-Release/dp/B002RL8FIE/ref=sr_1_1?ie=UTF8&s=hpc&qid=1291354212&sr=1-1)<br /><br />======================<br /><br />First, my product review<br /><br />Pros:<br />- Eliminates my snoring! (see below, your mileage will vary)<br />- The least expensive product (per mg) that I have found so far.<br />- Shipping has been reliable from this vendor.<br />- Product is 100% guaifenesin (no decongestent, etc..)<br /><br />Cons<br />- As previously posted by another reviewer, they can be difficult to swallow because of their size and the fact they are not coated. I have a large mouth :)  so not so much a problem for me, but those with smaller mouths/throats (like my wife) might have more difficulty.<br /><br />I have been taking Guaifenesin for the last 5+ years. My allergy doctor recommends taking it when I first notice allergy or cold symptoms as a means to help me combat the allergy/cold and recuperate faster.<br /><br />I used to snore often and thought I had sleep apnea (I don't, according to an overnight sleep study). My wife and I were both sleeping poorly from my snoring and our quality of life was greatly impacted.  She made this (life-saving!) observation that I did not snore when I was on the guaifenesin when I was taking it for cold/allergy symptoms.<br /><br />Given how guaifenesin is rated as a relatively safe drug, my allergy doctor saw no harm in taking it regularly and told me that, although it is not advertised to help address snoring, he could see how thinning the mucus (that I often have) would make breathing through my air passage easier and reduce the snoring.<br /><br />Guaifenesin might not help your snoring at all, but I would certainly recommend that you talk to your doctor if you have a snoring problem and ask if it makes sense to try it.<br /><br />Pierre
