I don't know why this product hasn't got more reviews. I recently got sick and decided I would try some new products. I tried zicam swabs, it was against my better judgment because I had a bad experience before with the zicam spray but it was recommended by a friend so I tried it. It did nothing. So back to the drug store I went sick as a dog with a head cold. I looked and read looked and read some more I finally decided to try mucinex expectorant cough suppresent. So far less than 15 hours it feels as if my cold is breaking up. My mucus has gotten thicker and instead of coughing all the time I'm coughing only when needed to cough up the mucus that has built up in my lungs. I hate the side affects of all cold medicine this is the only drug I have ever taken and not felt any side affects what so ever. Thank you Mucinex. 

Works great

Works better than Sudafed.
