I am on iv antibiotics and when I left the hospital my fev1 was 3.12. When I went to my follow up appt. Wed. night. My fev1 went down to 2.69. I felt so cleared up in the lungs I thought I was going to exceed my goal of blowing a 3.3 but I went down. I was so surprised. Apparently I have the asthma also and I was weezy and didn't even realize it. So the doc. wants to put me on predisone and I am afraid of the weight gain. Shallow yes. But I wanted to feel great on my trip to Napa in a week and half. I know my health comes first. But anyone out there who has been on it.
