i get colds and things like that a lot and i miss a lot of school, i was diagnosed with cf nearly two years ago and was only in the hospitol right after diagnosis, i have been very fortunate, i am sick right now and next month when i'm at the doctor i'm afraid he's gonna stick me in the hospitol, i'm really not looking forward to that dr. appointment right now, i've been worse but i've been better too, we'll see what happens. Usually when i get sick its when i have been off my meds, i'll get busy with something and not do them for a few days and start feeling like crap, thats probably my own fault and i'll pay for it later i'm sure but i'm lucky i can regain the pfts again by doing my meds. I hope this helps
