There's always the old classic, the true first energy drink. Jolt Cola. Twice the caffeine as a regular soda, and now it comes in a giant vacuum sealed cylinder that always seems to foam all over my roommate's desk.

The only other one of any consequence is Cocaine, which just got pulled from all the shelves, but will come back under a new name eventually. It was the strongest energy drink, period.

For whatever reason, I can't stand the taste of Red Bull and most of the other ones.
