Alcohol is cool and all but if it comes down to it a pure energy drink is xXx for me haha, here are the ones I've tried:

Red Bull
V
Zen Republic
No Fear
Rockstar
Monster
Shark
Sitting Bull
Lucazade Alert
Red Rooster

Anyone know any other that are nice?

Out of those above I'd say Zen/Red Bull/V only ones I'd have again
