I would suggest that you be careful about doing too much and too many different types of detoxing at the same time.
I would suggest you keep the anti candida and gluten-free diet, but avoid yeast killers while you're chelating. I would also suggest you be careful about which supplements you use too.
There are 2 reasons I suggest this. The first is because you don't want to be releasing too much poison into your body at the same time. Your body will be busy enough getting the metals out. The second reason is because if you are doing many different types of detoxing, it could be more difficult to tell what's causing any reactions you may have.
Anyway, that's just a suggestion. Let us know how chelation goes.
