The Daily Grind: What's your gamer fuel?

We saw this above image at our sister site, WoW Insider, and we couldn't help but wonder -- do these folks know their market or what? Personally, I'm working on my 3rd cup of coffee (hooray, hazelnut) and glad of both the caffeine and warmth considering a cold weather snap in my area. Our very own Moo Money is notorious for getting sugar-free Red Bull by the case because she likes the carbonation. Getting between Moo and her Red Bull can be a dangerous thing. We haven't tried the above "mana" potion elixir, but we've heard it tastes like Flintstones vitamins. (Of course, in a pinch and needing more energy, there are those among us who would probably drink one anyway.) Have you tried one? Do you like the pre-packaged energy fuel for gaming, or are you more the tea and coffee type? What's your favorite gamer fuel?
