In my experience, the candida went away gradually as I chelated.
Before I started chelating (i.e., before I knew that my problem was mercury), all my anti-candida measures seemed to be fighting back a never-ending onslaught.
After I started chelating, the anti-candida, antifungals, etc., worked and afterward the candida would come back much weaker than before.
Nowadays I can't say I have much candida symptoms at all, aside from the occasional digestive discomfort.
