Short-term energy booster

[b0b]

Caffeine doesn't seem to do it for me.

ECA gives me the pep I need, but if I take it too late in the day, I cannot sleep. I had to move my workouts to nights.

Is there an effective energy supplement that will be through with me within 2-3 hours?

Take a nap.

Not that I know of.
