What energy drink keeps you awake longest?

just from experience right now, i'd say Monster. I drank one yesterday at like 1pm and another around 7pm and took a bunch of b-12 and i didn't even sleep all night! i just cracked another monster about a half hour ago(they were 3 for $5) and i am so wired haha i'm even standing typing this. But i'm sure there are stronger ones. I know red bull is the most potent.

Well to be honest my brother in law works hard from 5 am till it's night time...he takes "5 hour energy drink"...lol and so do I...its a better alternative then taking red bull or monster...but if you really want to take something that is natural and doesn't have any bad chemicals...you should drink "X's" you can only buy the "X's" through a I.B.O. That works with Amway...it's good stuff and healthy too :) ...hope this helps you out!

I believe the best energy drink is called Crave energy drink? But you won't know till you try Crave out

monster extra energy

Emerge, or energe whatever it's called. I drink it at work and I can't get to sleep till like 3\4
