“Still can’t get over a heavy cough!”
could be post-infection inflammation ... he could try a 10 day (not 5-day) zith course ... zith is a powerful pulmonary anti-inflammatory and it won’t hurt him ...
"zith" is an anti-inflammatory? Really? Where did you get your medical knowledge?
5 milligrams of percocet, half in the AM and half in the PM might do the trick. Sometimes a nasty cough is a self-perpetuating thing, even long after your body has fought off the disease that caused it. Opioid medications kill the urge to cough and allow your airways to get some healing rest. I always hoard them when I can get my hands on some, along with any prednisone that comes my way.
