I've done some traveling, as well. Went to Peru in 2001, then all around Europe in 2003 (I live in the States). I just booked my first appointment today with a naturopathic doctor and am hoping to get some answers soon. In the meantime, I'm planning to follow an anti- parasite protocol using Black-Walnut tincture, cloves, and Wormwood . I will probably do this for about a month and then resume my yeast protocol (I don't think you're supposed to do both at the same time). As for Three-Lac, I don't really seem to be getting major results from it anymore, and I definitely have noticed that it can increase sugar-cravings. I just assumed that this was yeast die-off. I don't know. I've just kept using it because it really seemed to help me a year and a half ago, so I keep hoping it will have those same results again. I've heard many people say that it works well the first time but not the second. Is Grapefruit-Seed-Extract both an anti-fungal and an anti-parasitic? I'm using that now, as well. Also, if I dont' use Three-Lac, should I replace it with another probiotic?
