CarolynJHave you tried a partial elimination diet? You might try eliminating fructose (orange and other juices/fruit) and all artificial sweeteners for a week and see if you start to improve. If that doesnt' help, try eliminating lactose or wheat. You should, of course, have a thorough check-up by a gastroenterologist if you haven't already. I found some of the information in a book called Self-Help Way to Treat Colitis and other IBS Conditions by Delamar Gibbons, M.D. helpful but you should always check with your own doctor.Good Luck!
