have you ever tried doing The Master Cleanser , where you fast on lemon juice + maple syrup + cyanne pepper? there is forum on this site for it. perhaps instead of taking things that kill off various critters maybe giving a complete rest to your digestive system will free up your bodys energy to deal with the detoxing.
i have no experience with this myself . . . it's just a hunch.
you might want to post your question to andreas in his forum to get his take.
