5 hour energy?

I have never been a fan of all these "energy supplements" but I am seeing an ever increasing amount of ads for these "5 hour energy shots" literally everywhere
Every gas station has huge displays by the register.

Those other energy drinks did nothing but load you up on sugar.
well these other ones claim to be better

So lets hear your opinion. I haven't tried them but maybe I will if theres some validity to it but I doubt it.

Havnt tryd em. but if there anything like Redline, they are freaking insane.

yeah they work for me

I dont notice anything special except that I dont get tired. I don't feel any burst of energy and I don't get the "hot flush" from the niacin or whatever. I should probably mention that I drink about 5 cups of coffee a day on work days and never feel a buzz or get the shakes from it. Just the "tired" goes away. I guess I'm no help lol.

I've tried it, didn't do shit for me. none of them do anything for me though.

placebo effect?

No they work, but its not a rush of energy just enough to keep you feeling normally awake so you won't notice anything until you look at a clock and realize you should be tired. They don't work for 5 hours though...more like 2 hour energy.
