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.
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?
I ate fresh strawberries .. they seemed to work for me.
Gaviscon and Tums work well for me. Also milk of magnesia is pregnancy safe.
