Also, Arctic Pilot, from what I've read on the forum, until you get the mercury out of your system, you will be host to yeast - the reason being that yeast seems to ingest some of the mercury, thus protecting you. So, it seems that yeast will be with you for a while , but when the mercury is greatly lessened/gone, then the yeast will follow suit. As opposed to Steve's experience, I take probiotics in the form of homemade kefir, and am not, in any way that I can tell, suffering from it. In fact, I like to think that without it, I would be much worse off.
