I will be starting IBSrela soon, but meanwhile I need more help to treat my recurring episodes of terrible cramping & diarrhea for hours, now lasting for 2-3 days every week or two. Various diagnoses. What do you take for attacks of IBS diarrhea or colitis-associated diverticular disease? I have bentyl and levsin, each of which helps the pain, as does pepto or immodium. But is that all there is??
