Healthgirl, I hear you. I'm willing to explore any possibility that explains what's going on. For what it's worth, I read everything I could find on the issue and the best evidence for toxin binding and removal is on the side of Cholestyramine. I may eventually try it myself. Did you try activated charcoal? There is less research for it, for obvious reasons, but it does also seem to be less efficacious than cholestyramine. It seems quite harmless, well tolerated, so I would say it's worth a try. I will try activated charcoal at some point, after a couple of months of herbal antibiotics, antifungals and the like. Good luck and glad you've found a doctor who can at least support the path you want to take.
