Wow - Big guns! Helen, if I were in your place, I would really press the doctor to "back off" the 3 antibiotics to 3 times a week and see if you feel a little better. I think some of doctors really don't understand how awful the daily therapy is - for me it was FAR worse than every other day. Another option, which my ID doc let me do once, was a 2 week "antibiotic vacation" - it helped some as well.

Do you feel like your doc would be willing to do a CT to see if your lungs are improving, then consider adjustments? If you don't feel they listen to you, would you consider being seen at Mayo, NJH, or another lung specialty center?
