Dear Fellow RW ... BSers

I am in serious need of some kind of energy boost because, my get up and go has got up and went. Are any of these so called energy drinks any good? I've heard that Red Bull is kind of good but it tastes like a steel belted radial after 5000 miles of bad road.
Any thoughts?
Any suggestions?

Anything?
Yours truly
