Maxx, I can’t tell from your description how the antibiotics are involved. Do these episodes usually end by themselves, or do you generally start antibiotics to end them? How long a course of antibiotics do you take? Do you take just one antibiotic from that list? What does your doctor say is going on? Do you have urgency and/or increased frequency, or just watery stool? Are you gassier during these episodes? Have you ever been tested for C. diff?
