I'm not quite sure why you are taking charcoal pills as they are typically used for poisoning and such. I would stop those. Look into a good probiotic. Glutenings can last up to a month or so. Immodium should help with the D. Give your body time to heal...lots of time. Try to stay with whole foods and limit anything processed. Try not to eat out for awhile as you learn more about living gluten-free. I would not worry about other intolerances at this time as it is most likely to hard to tell at this point. Be patient!
