i am concerned that you have "serious" heartburn as frequently as you described and would like to know if you have been evaluated by a health care provider. i would also like to know if you have taken any over-the-counter medications and what their effect was. i don’t think the baking soda in water is harmful but i don't see any benefit either. i would highly recommend seeing a health care provider for further evaluation.
i have serious heartburn several times a day. baking soda in a little water gives me fast relief. is this harmful? . i have been taking a teaspoonful of it in water for several months now.
