+1 on reading that book.
I think Shoemaker has shown that a large % of people diagnosed as CFS were mold toxic, and I don't know enough about CFS to understand if the mold caused it for them, or if they were just misdiagnosed because their is a major overlap in symptoms.
If I were you, I'd be focused on treating the mold. Finding the source of exposure is probably the best thing you can do. As for treating, I'd go with what's in Neil Nathan's book but it's not the only way to go. Starting very slowly with a binder - charcoal, sacromyces boullardi, bentonite clay are all ochratoxin binders if I remember right.
