I just did the cleanse and I am a firm believer. I have had problems with Gallstones for over 15 years and have tried every remedy I could find and without results and some made me sick. I was told several times by doctors to have surgery or I was going to have problems. I was not going to let another quack cut on me again. Just 5 hours after doing the cleanse I was passing stones and feeling better than I have felt in 15 years. It was like somone pulled a knife from my belly, what a relief. So being extreemly sceptical as I am, take it from me, there is nothing to be afraid of. Unless your afraid of feeling better.
