I have only done three flushes. I followed the directions for the flush, ending with the Epsom Salt drinks for the first two. With my last one I followed with the salt water flush and found that cleaned me out really well. It's only been a week since my last one but I had such good results that I am going to do another one this weekend. My tongue has not been pink for years and today it is!!!!!!!!! It didn't even come pink after 28 days of The Master Cleanse but right after my Liver Flush I am going to do The Master Cleanse for as long as I can. Keep at it and you will reap the benefits.
