What kind of effects ought one to look for after consuming baking soda dissolved in water?

Loose stools would be the main one. Stomach upset is a close second.

The loudest BURPS heard around the world.

I do this all the time for indigestion, mixing ½ cup water with ½ teaspoon baking soda. It’s on the Arm & Hammer box. The only effect I notice is relief and maybe a satisfying burp.

For the price of a roll of Tums, I get a one or two-year supply of antacid.

Small dose engenders the burp. Larger dose creates the belch. Largest generates the magnificent greps.
