How does five hour energy work?

Wouldn't you get 5 hours with less effort?

You would think but no it's more like a buzz of energy and it wears off once it works through your system. So take less and less has to work through your system. So less energy.

Ok. I don't use energy drinks, so I wouldn't know

I only drink them when I know I have to do like a big thing like move or clean the house for spring cleaning
