Moved this from heart disease. I understand you are looking for help with an anti-toxin vitamin C protocol.
Pathogens produce toxins, and vitamin C is by its nature, one of the best "anti toxins." Dr. Levy's book PRIMAL PANACEA offers a theory why Vitamin C works against all toxins. He argues that all toxins steal electrons, and that is why enough vitamin C works to neutralize toxins by donating electrons. (where enough vitamin C is different for every person and/or toxin). In your case, you are up to 80 grams (at one time???) bowel tolerance. You may need more during the day.
Cathcart had experience that his patients sometimes reached 200+ grams, e.g. mononucleosis. You might only be about half of what you need.
So the first step is finding and hitting your bowel tolerance. And the more ascorbic acid you can take, the more likely it will enter the blood stream intact (from our bioavailability experiments.)
Others may have other "anti toxin" ideas, e.g. iodine...
