I don't drink soda, just never have. Once in a blue moon I'll have a ginger ale or root beer, usually with pizza, but that's it- they make me burp a lot! I was one of those kids who never had soda in the house while growing up, & I swear it's rubbed off on me. Popcorn I can eat fine, unless I'm flaring pretty badly. But again, I'm not a huge fan of it, so I rarely eat more than a few handfuls.
