One thing more. While there are many protocols to treat CFS, none of them appears to be a winner. You have probably heard about the Marshal protocol? It is quite expensive to follow, because the drug to lower D-vit in this treatment is expensive, and the die-off reactions have been harsh for some. The simplified Yasko protocol is actually a quite light one, with weak ingredients, I'm not sure how successful this has been. The Cheney protocol appears to be quite complex, but the whey protein approach appears to be successful. I think it's best to experiment yourself, if you understand more what you're doing.
