Cough and Nasal Congestion
"Serious relief from an aggravating cough that had me physically drained and in pain. But this is day two and 2:12am and yesterday I had maybe two hours accumulated sleep. Cannot switch my brain off and I desperately want to sleep!!! I suggest a day break between where you use DayQuil/NyQuil unless you want to experience what seems to me a crack addict feels."
