I understand. I would just keep in mind that more than a few people I've read about weren't able to do more than control the yeast through diet until they took care of the underlying issue causing the yeast problem. That has basically been my experience too.
I'm still in the process, so I can't yet say definitely whether or not getting rid of the metals will take care of my yeast problem, but so far, so good (with a few bumps and stumbles here and there).
