I did the flush 5 days just before surgery. I am more than a year after that whole time. At this very moment I am having a GB attack, or possibly a stress related back pain. Hopefully it's just back pain. I can tell you that my worst GB attacks have been after I started flushing. However, I have always gotten something out of my GB doing the flushes and am convinced that I am evacuating crap from my GB/liver. I have a lot to say. I will I.M. you or emails, or whatever if you like. I would like to think you tried a flush before you did surgery. There's so many reasons to try it. On the other hand flushing will get you into a life of liver and GB cleansing that you wouldn't otherwise do. user Spleenpain who has had his GB out said that he felt the GB was the 'heart beat' of the liver, pulling waste out of the liver and dumping it into the intstines... He wishes he didn't do surgery.
