LindaLou, I'm also a sufferer of small amounts of mercury. However, if you can't tolerate ALA, and e.g. get spaced out when taking it, you still have a problem. Your symptoms after removal was those of candida, and similar of what I had. However, you don't get rid of candida in half a year with those initial symptoms, it takes a longer time. So you still likely have candida. Continue to chelate with ALA until you dont react to it. Use low doses if you can't tolerate it well. In the end you cant consider yourself cured until you can tolerate ALA, because all healthy people can take 100 mg ALA without noticing anything special.
