As blasphemous as this may sound, I prefer LiveWire and Pitch Black over regular Mt. Dew. I just got burned out on regular Dew rather quickly.
Then again, I like a lot of orange & grape sodas (and actual lime ones as well; not lemon-lime, but lime). I'm a big fan of ginger ale, root beer, & red sodas (ala Big Red).
But, my main addiction is Coke. Mainly Coke classic & Vanilla Coke. Liked Diet Coke with Lemon (& the Lime variety), but I'd love to get a regular Coke with Lemon (or Lime). Don't often drink Pepsi (though I do like Pepsi Twist, since it's the only regular cola w/ lemon that's available at the moment).
Mt. Dew sorta is a staple of our gaming group, but the master of the gaming-night beverages is Dr. Pepper for our group. I occasionaly drink it (not a big fan of the stuff myself--like I said, I'm addicted to Coke), but it's pretty much the caffeinated, carbonated drink of choice.
