What are the best alternatives for a burning stomach ?

Sounds like you are in a world of hurt I, feel for you. One person suggested apple cider vinegar and another an OTC called Aciphex. I believe if you combined these 2 recommendations you'll feel much better. Herbal teas are good too but if they contain caffeine that could counteract the effects of the antacid and cider vinegar so you should stay off the tea for a little while but, only if it has caffeine. No sugar either, just nature's sweetness from fresh picked fruits. Hope you get better! God bless you.
