For Cough and Nasal Congestion "I read the reviews on Mucinex and was a little concerned, but I was also desperate. For 2 months, I had a thick postnasal drip that would cause me to constantly cough, especially at night. I had to sleep sitting up in my chair in the living room. I was wheezing, had a runny nose, and was coughing up tons of mucus or clearing my throat from it. I took one tablet at 8 a.m. and another tablet at 8pm OMG, I can clearly breathe with no wheezing, congestion, or mucus getting in my way. I slept through the night, and when I woke up, my nasal passages and throat were clear."

For Cough and Nasal Congestion "I took two pills at 3:00 pm, I fell asleep around 10:30 pm and woke up wide awake at 1:00 am! I'm still sneezing and coughing, but I'm feeling better than I was before, so it works. But now I'm wide awake and can't fall back asleep, and I feel funny, like my heartbeat is slower. I sure hope this feeling passes!"

For Cough and Nasal Congestion "Awful as I'm writing this. It's 1:30 a.m., and I am up, and I can't sleep, and it made me cough so much more! I have a baby, and now that I can't sleep because of this medicine, I'm going to be miserable tomorrow! I don't recommend it to anyone!"

For Cough and Nasal Congestion "It dehydrates you like crazy, and I could not drink enough liquids. My throat got so dry it caused me to cough uncontrollably. For the past 3 nights, I could not sleep... Even took 10 mg of Ambien, which usually knocks me out cold... But it didn't work. I just found this site and learned that my insomnia is caused by Mucinex D. Not worth the lack of sleep!"

For Cough and Nasal Congestion "This stuff is torture! I was coughing a little and had some allergy congestion. The pharmacist recommended this stuff. It's 2:00 AM. I took two pills at 3 in the afternoon, and I have been coughing my lungs out ever since. I'm literally coughing so hard, I'm sweating and have a headache. I feel edgy, and there is no hope of getting sleep tonight."

For Cough and Nasal Congestion "I took this around 9 p.m. I fell right to sleep with no problems. It did not keep me up at all. I woke up and blew my nose, the medicine had worked. It cleared my nose after I blew it. However, the taste is disgusting, and I still have a cough."

For Cough and Nasal Congestion "Made the cough go away, two days later and zero hours of sleep. Give me the cough all day. Honestly, these things make you feel like you’re on drugs. If you are trying to achieve a legal high that you can buy at the store, this is for you. STAY AWAY FROM THIS THING."

For Cough and Nasal Congestion "Took one pill at 8 pm. It’s now 3:32 am, and my Apple Watch just calculated a 116 bpm heart rate. I’m also coughing so hard my rib is twinging. I think this drug is a hit or miss... my husband, who took it, is sound asleep next to me."

For Cough and Nasal Congestion "Well, I too am up right now, 3:07 am. I thought it was my cough, which had a lot to do with it, but I was laying down, causing the drip. Weird dreams, yes."
