Hi,I've used Colpermin (peppermint oil capsules), and while it didn't get rid of the D, it seemed to reduce the cramps and pain. The downside of this was, that while I was taking Colpermin, the D attacks would come really out of the blue -- without the warning cramps. I think that despite what they say about it, Colpermin would be of more help to IBS-C people.Ge.
