I just read on a website that 3percent hydrogen peroxide, and saltwater is the best and cheap. mix 13-30ml of 3percent hydrogen peroxide into a solution of 1 tablespoon of salt mixed into 1 litre of water. Drink this down within 10 minutes in the morning. after one hour introduce friendly bacteria such as those found in live yogurt cultures. Eat 1 or 2 cups of yogurt. You may need to do this as little as 3 days or as many as several weeks. I just tried it and drank about 8 oz. before i almost vomited. I am really bad when it comes to swallowing things. (smile) but with only the little bit I can feel the bowels moving.
