Mix 1 teaspoon of baking soda with 1 cup of water. Drink immediately. It helps with sour stomach, nausea and acid stomach only seconds after drinking.
I keep this mixture on a nightstand in a small glass jar. If I need it during the night I just shake it up and take a swig.
It works faster than Rolaids or any antacids I've ever tried.
