I just finished 10 days of Cipro with side effects of insomnia and diarrhea. I'm exhausted. The symptoms of low grade temp and amount of sputum are less. We'll see what the Infectious Diseases Doc has to say. I think the plan will be to not worry about the relatively inactive MAC bacteria and concentrate on the more opportunistic bugs like Proteus. I hope I don't have to go on a maintenance schedule of antibiotics! I think it is interesting that there seems to be a trend not to try to "cure" the MAC with the big 3. It doesn't seem to work. robynmar
