Gaviscon and Tums work well for me. Also milk of magnesia is pregnancy safe.
I ate fresh strawberries .. they seemed to work for me.
What's gaviscon? Never heard of it. Also why is it that sprite, Sierra mist and 7 up seem to help? Is it the carbonation?
Gaviscon comes in tabs like tums or in liquid form that feels like you're drinking toothpaste. It's very thick but it works instantaneously. It's a bit stronger than tums.
