cough
"My husband had a nasty cough for days that wouldn't go anyway and kept him up all night. He tried a couple different over the counter medicines but his cough increasingly got worse. Someone recommended Delsym which he tried and FINALLY he got the best night's sleep...not one coughing episode all night!! I would truly recommend to anyone who's sleep deprived with a nasty cough and worried spouse."
