I know we're not supposed to have any cokes, Pepsi, etc., but I found some flavored water with 0 everything but it's carbonated. No caffeine, no calories, no nothing. I am having trouble drinking plain water as it gets me so nauseated and I don't know why. So my question is why can't we have anything carbonated?

I was told the carbonation will expand in your stomach causing it to stretch. Which is what you don't want.

Okay, thank you. I didn't know that. It really helped me burp which I was having a problem with, lol. I won't drink anymore.

Yes, the gas takes up too much room in the stomach.

that exactly right, the carbon can cause your sleeve to stretch
