I once took a five-hour energy shot plus a can of Monster...my wife said I was talking like an auctioneer and I remember my head buzzing and rapid eye movements. Time seemed to slow down a little bit.

I only did that because I had a hot load and it needed to be delivered yesterday (literally). I was getting sleepy and the soonest my student could take over was five more hours. That cocktail worked to keep me awake and alert all right but I don't do that anymore, I just get more sleep!
