I have an 8 day old cough from a cold...Wet but not produtive. Used nyquil guaifenesen (sp) and hycodan (hydrocodone)....Gotta skeep... Benedryl next?

See a doc. My colds and coughs last a while too. You might benefit from a Codeine cough medicine, but see a doc and have it checked out. Don't wait if it is pneumonia. Benadryl (diphenhydramine) may really dry you up and make your symptoms worse.
