Thanks Raney.
I was on antibiotics for MAC and am aware of the diarrhea issue. I unfortunately had extensive radiation for cancer years ago which destroyed my digestive track.
To make it worse, the radiation caused a cancerous colon tumor and the surgeon removed lots of both my small and large bowels - cut happy doctor! He said it was so damaged by the radiation that it wasn't doing me any good. Wrong!!!! I have had diarrhea and pain since the surgery 6 years ago.

When I was on cipro I couldn't leave the bathroom and that was before the colon cancer surgery. But I'm willing to try it if it will help me breathe.
