cough and nasal congestion
"So, I am not one to take medications much and I don't take any medicine on a regular basis, but Mucinex D is definitely a must in my medicine cabinet for that severe once a year bug. It CAN cause sleeplessness in the night but with that in mind I usually take it at 7 am and 7 pm if I even take a second dose at all during a 24 hour period. I cannot sleep when I get a cold and though this medication can keep me awake, it is still a better alternative to suffering through a night of clearing my throat and getting up to blow my nose multiple times. For the record I only take 1 at a time and have quick results with no other side effects besides the sleeplessness. Choose wisely y'all, this stuff can be a miracle if you need one."
