Hey, I've kinda had my symptoms change so I don't have IBS C much anymore but this is one thing that always worked for me. With any kind of Dieters tea I always had a normal BM about 7 hours later. I usually drink it at night and then first thing in the morning or some time the next day it helps me go to the bathroom. I'm not sure how safe it is for IBS or what it has in it but I would think things like the Dieters Green Tea have pretty natural ingridients and would probably be better than traditional laxitives or other methods.Anyone else have good luck with it?
