You may be on to something there. 20 flushes is a lot. I have wondered the same thing so I have tried a number of things to speed the flush along. I have tried chinese herbs, Malic Acid, Apple Cidar Vinegar, lecithin, homeopathic remedies.
One thing I am about to try is parasite zapping before-hand which I have not yet done. Maybe this will help. Thanks.
