I tried my first flush over a year ago and got probably 50+ green stones out. My second and third attempts failed to get out any more stones, but unltrasound confirms I still have many stones. I have scheduled gall stone surgery for Monday, July 22, as I have had several severe attacks in last month. I really wish flush had worked for me, but it seems that some cases are truly not curable/fixable with the flush. Any last minute suggestions before I go under the knife?
