For Bronchitis "Took this medication for a chest cough before I went to bed. Woke up in the night with severe nausea and felt dizzy. Tried it again a week later and the same happened. I know other people who swear by it."

For Bronchitis "I'm not sure Mucinex works. I know it kept me wide awake. It was hard for me to sleep. When I was awake, I felt like my balance was off, so I felt dizzy. I couldn't go down spiral steps. I would not recommend it."

For Cough "About an hour and a half after taking one Mucinex DM, I developed severe dizziness, drowsiness, bad intestinal cramps, vomiting, and diarrhea that recurred over a period of 2 hours. It was the only medication in my system."
