That kind of sounds like a herxheimer reaction. I don't know if vegan is the healthiest choice for everyone. I guess that is what the Debate Forums are for. But, it sounds like your body was trying to eliminate toxins and wasn't eliminating them fast enough and the release and re-exposing them to yourself might be a large factor. Infra red saunas I heard are helpful or just helping the detox pathways.. coffee enema's, liposomal glutathione. It's a tricky business. Just my thoughts..
