Last night, Nick and I tried that 5 Hour Energy stuff.
It comes in many flavors, but the kind woman at the gas station chose two grape flavored bottles for me. The directions told us to drink half for "moderate energy" or the whole thing for "maximum energy," so we threw caution to the wind and downed the whole thing.
Results:
We took it around 8:00 PM. As for the product's claim that you don't crash afterward, I can not really speak to that except to tell you that I was still wide awake when I got under the covers at 4:00 AM this morning.
5 Hour Energy: That shit is bananas.
