If you didnt use salts with the Liver-Flush then the stones didnt get flushed out of the digestive track the next morning. They eventually worked their way out with regular bowel movements. Your asking for trouble if you do the Liver-Flush without salts to relax the bile ducts. I would suggest drinking large amounts of fresh AJ to shrink the stones for a week before doing a flush without salts.That might be why you had back pain. Fasting is something that you should learn slowly and always take great effort in helping the body eliminate toxins. Drink alot of fluid,sweating,SWF,hot baths,saunas,deep breathing,expose skin to air,skin brushing,etc..
