Thank you for responding. I decide to stop the cleanse today because I can't deal with the pain. I already did Dr.Schulze's cleanse about 1 and a half weeks ago and still had this problem. I am not allergic to his stuff either but I get severe pain on the left side,near the colon and running through the leg every time I have a major bm! I'm thinking of getting colonics with a therapist that a friend recommended. As well I odered some of Natren's Megadopholous. Are Udo's choice products good for probiotics?Thanks so much for the help!
