I did The Master Cleanse before I did the liver flush. I did the cleanse for the recommended 10 days. I don't feel that I got a good results from my flush, I did pass a few small pea size stones and the next day a few larger stones. But, because I wasn't eating I didn't feel I had enough (whatever is needed)to help with the elimination process. This is just what I have experienced. I'm doing another today I'll see what results I get from this one. God Bless hope this has given you answers you were searching for.
