I have done many fasts, but only once I had diarrhea for a few days. Eat plain brown rice and plain yogurt for a few meals. Also have tried taking probiotics?
Another thing can help is Millet bread, but it is hard to find and hard to make. If you have Indian store near you they may have frozen Millet bread. You can eat that with yogurt and it should bind your stool.
Also try plain
water enema and then
coffee enema to clear out your colon.
