I'm very pissed at myself, 2 weeks ago I had my clinic vistit and my PFT's were down 25% and couldn't figure out why. I feel great, not culturing anything abnormal, exercising more weight is up. My dr and I agreed we'd give it 2 weeks see if anyhting changes, started doing more cardio and vest 2 times a day. Went back to day and no improvement so I'm going on IV's for the 1st time in 9 years.
