I tried the gallbladder flush and it made me feel really sick for many days after. But, I have a gallbladder that is not functioning up to par, so that could be one of the reasons. I did pass some "stones" that were soft and puddy-like, some were pretty big (1/2 inch). I haven't really decided whether I think this thing works. I have done a lot of research on it. I guess if you do it enough times, you will probably eventually get gallstones out, if they are not too big. Try curezone.Com, they have a liver flush forum there. A lot of anti-surgery people, but some info about the flush from people who have done it.
