Mine was so bad I got a prescription from my doctor. Helped a lot!
Try a couple teaspoons of baking soda 4- 8 oz of water (it tastes a little odd lol). It'll make you belch, but the alkalinity of the baking soda will neutralize the acids in your stomach :-)
I had it so bad I ended up in the hospital .
Yeah mine started last week. Was so painful. I went straight out and bought Tums. Its been great.
