Do you have chronic bronchitis? In my case, a cold frequently turns into 6 weeks of coughing. Get some guaifenesin (Musinex or OTC generic tablets) drink lots of water.
If it's dragging you down, waking you up at night with coughing...ask your doctor about Tessalon perles. They look like little football shaped Vitamin E gelcaps.
They work well, and don't cost much (non-narcotic prescription)
I have got a narcotic prescription cough medicine now and I hate it,doesn’t work well.I’m into 4 weeks already.
