In addition to what Dr. Bailey said, if you have both candida and parasites, chances are you have leaky gut syndrome too, which many if not all of us have. Most people don't realize they have it. Until you get your leaky gut under control, you will never fully get rid of the yeast, parasites, etc., because the leaky gut makes your body essentially open to all sorts of things like that. I have the same problem. I was diagnosed with it years ago but I guess I never realized how serious or important a factor it is to getting well. I am going to be taking a supplement that helps me to break down proteins that I eat. This is essential to healing leaky gut. People with leaky gut can't really break down proteins and the undigested proteins become fermented and wrotten and a lot of that mess passes through the intestinal wall and starts floating around in your bloodstream, wreaking havoc, lowering your immune system, etc. You can read about it anywhere on the net. Anyway, like I said, heal your leaky gut and everything else should fall into place, with regards to getting everything fixed once and for all.
