Here's what to know about these multitaskers:
ENERGY BREWS
Sparks (Miller Brewing Company)
Tilt (Anheuser-Busch)
What's in It: As much caffeine as a cup of coffee, and a bit more alcohol (6 to 7 percent) than beer
What to Know: Lets you party longer, but there's a catch: Alcohol wrecks your body faster than your guy's, so partying longer = more alcohol = more damage.
CAFFEINE-INFUSED VODKAS
V2 Vodka (Wingard; v2vodka.com)
What's in It: Caffeine and taurine, the essential amino acid found in Red Bull and other energy drinks
What to Know: Caffeine helps you burn a handful of extra calories, but don't consider this your new diet plan.
