bronchitis
"I am on my second bout of pneumonia. The constant coughing is painful.  I bought this drug otc, and it is helping, a lot. I feel a bit dizzy but I will take dizzy over that constant hacking cough any day.  I got this because it only has the "mucus" drug, without the extra junk in Musinex I don't need.  The best part? For 15 tablets, cost only 88 cents!"
