James, I'm sorry to hear this but I've been there and still go there. The ONLY thing that helped me, and I'll be repeating myself for the umpteenth time I know, but was a strict candida diet with healthy foods and fats.

Anything else was either ineffective because my body was yeast overloaded and too ill to absorb anythign anyway, or I would react badly to it, supplements included.

Diet reduced yeast and improved some mental functions and the anxiety and depression often improve or even lift significantly. Anything outside of that to my mind is just additional as far as supplements/herbs go.

Apart from that? proper chelation. Because if it is metal related, then this is the only way to really cure the underlying problem. If I could think of a quick fix? I'd give it to you. I know of none.

The diet may not be appealing in the respect of giving up most foods, particularly sugar, but for me it was either that or probably ending up institutionalised. You may already be on it and I apologise if this is so. But if not, I'd do it immediately.
