cough
"I had a persistent cough for 8 weeks (muscle strain in side and back the worse pain ever when I coughed) diagnosed with walking pneumonia and was prescribed the usual Tussin with codeine (and an antibiotic) which is never helpful to my cough, after going to urgent care a 2nd time I was prescribed Tessalon (and another antibiotic) I took it 3 x day for 3 days and my cough started to cease by the 5th day no cough...2 weeks later cough started up again due to cold air, drafts at work so I read up on Tessalon that it starts to work up to 20 min after taking...maybe not 20 min for me but by end of day no more coughing."
