The anti-candida diet and supplements haven't cured me either. My candida overgrowth refuses to be cured. It finally dawned on me that mercury overload is most likely at the root of my problems. I think that could be the case with you. I can't answer your question definitively, but I can say I have a similar situation to yours. I'll be getting my fillings replaced as soon as I can.
Do you have anymore mercury fillings? If not, are you planning to do a mercury chelation program to get the mercury out of your cells? That would probably help, but you can't have any mercury fillings left or the chelation will pull it out of your fillings and you'll have much worse symptoms. Do a search on curezone for mercury toxicity and the chelation protocol.
