Yeah I'm gonna try Cape Aloe Crystals too I think. The name alone is cool!

1 teaspoon is good advice for the baking soda. It tastes pretty awful, but it does work. When the burp comes, you'll feel better. It's so strange how it works, but it basically just neutralizes the acid and gas builds in your stomach :P For me, a teaspoon won't touch it, I have to take a tablespoon, and it makes me a little nervous, because that might not even be safe.

Definitely start small and be prepared for a not so pleasant flavour.
