I had two half day long gall stone attacks and chose to do the flushes. My sister and Uncle and Grandmother all had their gall bladders out. My sister and Uncle regret it because of major disruption of digestion. I have done over 23 flushes now, I can digest anything. I pass only what looks like sludge when I flush now... and the benefits of having a cleaner liver and gall bladder are just huge. The apple juice and apples and malic acid will shrink any stones they can.... time will be on your side if you choose this route. I passed stones of 3/4 an inch around the rocks durign fluch 3... and took pictures.
