I have read lots of past postings in which people do as many as 15 cleanses and suddenly have great results. Certainly if you are passing parasites your already doing miraculous things for your health. Keep flushing and maybe one day you'll be surprised at the results. Maybe your like me who has bigger stones and you'll have a breakthrough. I get those little pieces lately and get discouraged, but am convinced I will have a breakthrough soon. Keep flushing!
