I was wondering about Clarkita, from Dr. Clark. How long do you have to be taking this in order to actually get any results? Does it actually kill the parasites, or just flush them out, or what? I have heard to expect some "ill" feelings while taking this because it's killing the parasites, is this true? How bad?! (I have to still be able to go to work). Wht about my kids, can they take it, and how much? Is this the absolute best parasite killer on the market, or are there others just as good I can pick up from my health food store? Can this product be used without doing those cleanses and still kill or get rid of the parasites? You see, I work 2 jobs, and never have a day off, so I really can't do those cleanses! Well, thanks to anyone who can help! citygirl
