Thanks. I'm in my 3rd antibiotic this week. Prednisone. If I have cf.. Will this help some? Sorry to be asking a million questions.. I just most likely gonna be going back to work tomorrow.. It's a physical hot job. Been on short term disability for the last week and a half and don't feel better with shortness of breath. Coughing etc... I wanna go back to work but I know I'm gonna feel like crap... Spoke I could go to the Dr. And have him extend it. But I'm also tired of being stuck inside... Dshdjdd. This sucks
