this isn't personal experiance, but my dad had the nastiest gallbladder attacks . . . to the point of going to the hospital cause the pain was so bad. . . . he told me that while he was doing the flushs, he never felt any pain. and as he continuted with them i do believe the galbladder attacks became less intense. . .and now he doesn't have any.. . (i think he did 12 flushes before he could eat anything he wanted again)
