I completed my first flush over the weekend and all went well. I followed the instructions in Andreas Mortiz's book "The Amazing Liver Cleanse" and got about 30 stones ranging in size from lentil to pea. I had no discomfort other than the Epsom Salts were hard to get down. I'd picked up some tips from lurking around here for the past few weeks so I dropped the amount of salts to 2 tsp per dose rather than the full 3 and I added some juice and that helped.
Thank you to all who share your information and experiences.
