Mucinex D
"It's 3 am, and I'm wide awake. Took Mucinex at 1 pm this afternoon which helped relieve some of the pressure in my head caused by congestion. Took NyQuil at 9:30 pm, hoping it would knock me out like it usually does but no such luck. I only took 1 pill at 1 pm yesterday, but I guess since it's a 12 hour medicine and I'm a small female (103 lbs, 5'4"), it's still affecting me a lot. My husband swears Mucinex made him feel better but I say no thank you. I'd rather blow my nose all day and be able to sleep at night. Will not be taking again."
