Get organic stevia that contains no other ingredients other than stevia. You can have it as much as you want; the only negative consequence is that it causes a mucuous reaction because its so sweet. Mucous production can coat the candida, making it hard to kill. However, me and Able have had it throughout our diets with no noticeable consequences. A sprinkle of cinnamon won’t set you back too much I believe, just don’t overdo it.
