Redbull and Vodka

Redbull seems like it helps...Guesss what, it doesn't.
"Results show a considerable disconnect between subjects' perceptions and objective measures of their abilities: although combined use reduces the sensation of tiredness and sleepiness, actual capabilities are significantly impaired."
Well at least when we're talking about mixing it with alcohol - I love the stuff. Actually, I've found something much better than Redbull - Zipfizz (more natural - less caffeine)
