I was thinking of something that Agnes said recently. Someone was talking about not getting stones out, I think, and she said that it was our liver's decision when to release the stones. And that sometimes our liver may be really in need of cleansing and needs to heal before it can fully release stones. She said that some people had not seen "the big one" til their 18th or 19th cleanse.
Maybe you don't need to do anything spectacular in order to remove the stones. You just need to keep doing it. I know I was disappointed to not get stones out on my third (just chaff) and fourth times(nothing). I almost didn't do a fifth. Who wants to go through this with no results? But I decided to do it once more and that day just happened to read what Agnes said about not always getting stones out.
Like Rachel said, everyone is different. We are all at different stages of wellness. We all should read what others have done but do what we feel is best for our own situations.
I have never had a gall stone attack but several years ago I had kidney stones. Yikes! EXCRUCIATING!!! After reading your post, I really felt for you.
