For Cough "Week two of nonstop coughing and 3-4 hours of sleep a day. Tried tons of over-the-counter stuff, and nothing worked. Went to the clinic. Doc said bronchitis, so gave me this cough med and some other stuff. Second day, and while not coughing as much, it still gets really bad at night. Six hours of sleep last night felt awesome, but it was two 3-hour sessions broken up by a 2-hour long coughing spell. I’d say it’s just not a great help, but it’s something. It’s 1:30 a.m., and I’ll be awake another 2 hours or so. Depressing!"
