I will tell you that I don't drink soda.  It's a long story, but basically, when I was a kid, my best friend Tracee had ADD and wasn't allowed anything sugary.  In solidarity I stopped eating stuff with sugar in it (that's the story my mom tells me).  These days I'm more of a chips and queso kind of girl.

This video is by Crack Russian Hacker and about what's in Coke when you boil the liquid away.  It's pretty disgusting.
