For Expectoration "Took an off-brand Mucinex around 10:00 pm, (same ingredients). I fell asleep and woke up at 2:00 am with extreme anxiety, dizziness, rapid heart rate, diarrhea, nausea, dry mouth, and shakiness. Will never take this medication or anything like it again. I'm glad I only took one tablet."

Dextromethorphan / guaifenesin for Cough "I have a cold with a cough, some post-nasal drip, and congestion. I took this before bed, hoping to calm the cough and get some of the stuck mucus out of my chest. It did help me suppress the cough, but also made me wake up at 4 am with a panic attack. Fingers tingling, face numb, heart beating crazy fast, and feeling nauseous and dizzy. Unable to fall back asleep. I have had a similar reaction with dextromethorphan before, but not since I was a kid. I don't recommend taking this if you have adverse reactions to sleep medicines or other sedating medications. I often have the opposite effect with those meds, and this was no different."

Dextromethorphan / guaifenesin for Cough "I purchased a bottle of Mucinex DM. Took one cap as directed every 4 hours. After the third dose, the headaches got very bad. My heart rate was very elevated. I could not eat as I would throw up anything I ate."

Dextromethorphan / guaifenesin for Expectoration "Taste was terrible and gave me a really bad aftertaste that I couldn't get rid of. It also made me really nauseous. I would not use it again."
