Super8,
Have you tried lomotil, its used for Diahrea and it definately slows down the colon so your rectum doesn't get as irritated. IT is an opiate. I always use it when flaring because I find the more I go the worse my rectum gets, plus when I take it I can at least function during the day without having to use the washroom so often. It also helps me to retain the enemas in the evening without my colon spasming, therefore helping it to heal.
