Never heard of the "club mate hype" before. Would that be yerba mate drinks?

Edit: Just dug a bit more. Yes it is, carbonated and mixed with some sugar. Yuck. I prefer my yerba mate the traditional way, thank you very much. Also, what's with everybody's obsession with caffeine and productivity? Why not just inject adrenaline right into your heart? Come on, people should use some "more common sense" and not overuse these substances.
