All those energy drinks will destroy your liver and kidneys.  That being said, I can definitely tell the difference between caffeine, B-vitamins, and other "give you wings" supplements.  Maybe my body is just getting sensitive.  I've never seen it in a drink, but Yohimbe is a great stimulant if you have circulation problems...it's like viagra-lite, too.
