Bex, I too get horrible yeast from trying to detox metals, infact it almost makes me nuts alot of times, in the morning at around 8 or so especially! My mind races and I have trouble breathing, a classic yeast flare up when I choose to chelate metals. Antifungals can damage the liver, but what kind? Cayenne I would not really consider that or would it damage the liver, infact that could help IMO correct? I agree though some can and it's dangerous over time. Have you ever tried Milk Thistle when chelating or killing off yeast? Probably helps alot. When I kill the yeat I get a metallic taste too and relase toxins in my body, it sucks and I feel flat out horrible alot of the times whether just a simple Probiotic or whatever. Enzymes are supposed to really help, but I took them and notta, didn't help out with the Yeast overgrowth and the ones I took specialized in that (Candida yeast management from NSI). I am going to get this and parasites down to try a metal cleanse again, seriously if I just go on the metal cleanse it sucks and I feel ALOT WORSE, almost crazy and very tired and so on. Yeast cleanses or getting yeast down always makes me feel alot better (I took threelac in 04 and felt better than I did in years, I could eat alot of things again), so maybe for me it's more yeast than Metals? Who knows, but I have to find out if I am to get better. I can think clearer and I am more positive with low yeast, as my yeast goes I go is my motto and has been for years. If Yeast is low I work very well and get alot done, if Yeast is high I work slowly and can't think straight.
