I've been struggling with IBS and Celiac for a long time. I still get cramps even though there is no more gluten ( or hidden gluten) in my diet.
I found a softgel that has peppermint oil, fennel and ginger in it from iherb. Wow, do these things work great and really tame the tummy!!! I finally have some relief! I take 1 at night and one in the morning. If I still get painful cramps, I take another one. They don't help with diaherra though.
They are a bit hard on the stomach at first so take with a bite or two of food until you get used to them.
