Mucinex
"I took this attempting to get rid of a cough and chest congestion. I am a 105lb 30 year old female. I took one pill yesterday and felt a little better. That was a half does so today I tried 2 pills, a full dose. After feeling nauseous for several hours I finally threw up several times and am feeling much better. I will not be taking it again, and would rather allow the congestion to run its course."
