I've been wondering the same thing!! Started Master-Cleanse on Sunday night and kept reading about stuff. Turns out, I've read that you must first get rid of parasites, then do Liver Cleansing (that it's actually dangerous to do the Master-Cleanse and/or fast without it!), then gall bladder, then bowel, and THEN do the master cleansing. What crap! Someone's just trying to sell stuff. It will be cheaper for us both to go buy the Master-Cleanse book then to listen to all this stuff. Anybody want to help us out here??
