I followed these directions except only used lemon juice instead of grapefruit, which is recommended for people with candida. Oh and I didn't "zap", I don't really know what that is and I don't have one. But in these directions it says that is to help kill parasites and the modern herbalist protocol for candida is actually a candida/ parasite cleanse, so I knew I was in good shape to do the liver cleanse. Oh yeah and also I think they mention 'ornithol' or something to help you sleep? Which I don't have 'cause I don't know what that is either. But for the record I never had any trouble sleeping on any liver flushes. It doesn't taste pleasant, the Epsom Salts or the olive oil/lemon juice concoction, but my attitude is that it's medicine. When did medicine ever taste good? And dimetapp and children's tylenol doesn't count. They didn't have that crap back in the day when I was a kid =) Plus it's only 2 days. A cleanse that lasts 2 days/ really just a day and a half. EASY-PEASY.
