they build it up just to burn it back down

i'm continually baffled at the phenomenon that is being-so-tired-you-must-sleep, yet-you-are-unable-to-sleep-because-your-brain-will-not-shut-up. there's probably a scientific name for it, but since i am suffering from the after-effects of such a night, i feel too muddled to look it up.

perhaps a second coffee, AND THEN A THIRD, is in order?
