Yes, I have used it and it works! I have used it for years and now, only when mold sypmtoms appear. When I get into a moldy envirmonment, my elbows begin to hurt (painfully) and I use Cholestyramine at night only for several days and the pain goes away. I originally used the protocol for Lyme disease which I've had twice. Get a presciption and take it! You will be glad you did. And if you can see Dr. Shoemaker, do that too. He treated me for the Lyme and the mold. It's the toxins that will debilitate you and they are easy to remove with the Cholestyramine. Good Luck!
