cough and nasal congestion
"Have not had sleep for two nights because of terrible cough. Took Mucinex D today at 2 pm and felt good. Like a new person. It's now 11 pm and cough is back so another night of no sleep. Do I take another Mucinex D at 2 am? Don't know if it will keep me awake or not. Choice: continue coughing with no sleep or no coughing with no sleep! "
