cough
"Cough kept getting worse at night so doctor had me start this medicine and I stopped the Tylenol cough and cold.  First night I was up at 4 am with dry throat, dry eyes and a bloody nose.  Took another dose with water and it took almost an hour to kick in.  Second night I didn't seem to help at all, kept coughing and was probably worst night of all.  Waited for dose to wear off then went back to Tylenol for a good night sleep."
