I've had this for years, tried all kinds of dietary changes, meds, supplements. Nothing worked. I tried Align (probiotic OTC "bfodobacterium enfantis 35624" "Bifantis"), 1 capsule a day for many months, and got no help. I doubled it (okay with Gastroent.), and within a few weeks felt much better. That was 6 months ago. I seldom have a bad day, and most days feel so much better. Gastroenterologist said IBS was almost impossible to treat as everyone is different, but studies have found that Align has been clinically shown to help specifically with IBS. It IS expensive, but it's worked for me. I think it's worth a try.View Thread
