well i've been dealing with some bad pft's. i don't know why i'm back in the high twenties. i'm usually in the low thirties. i think i might just be having a bump in the road. my weight is fine, my sats are fine, and i even went to seaworld and walked the whole park and didn't take a break. i have no clue why i do so bad on that test. i feel like my lungs freak out when they know i have to do the test. well i'm on a research study but not for new meds. just on tobi and cayston to see if that makes a difference in my lungs. this is a short post. will update soon. my next doc appt is in april.
