In Canada, we say "pop" teehee "Soda" sounds pretty funny.
Maybe that's where we New Yorkers get it from, lol. Born and raised in upstate NY - the Niagara Falls area - and now that I'm in the south, people look at me funny when I say "pop."
Anyhow. Pepsi is my go-to. When I get tired of that, I'll also drink Sunkist/Fanta/other orange pops, Squirt, various flavors of Mountain Dew (especially Livewire), and Vanilla Coke.
Really, the only pops I don't like are most of the lemon-lime ones. Sprite, Sierra Mist, Seven Up.. I dunno, they just taste sticky. They're flavorless to me and they just leave a sticky, icky feeling in my mouth.
I tried to drink more fruit juices and vitamin water for awhile.. But they all have roughly the same amount of sugar in them (often times more than pop does), so I just went back to my usual rotation of Pepsi, Soy Juice (it's not milk), and water.
