...it's all in the reflexes
My auto-pilot seems to be pretty well-tuned: I only got 2.5 hours of sleep last night (and a 20 minute attempt at napping in lieu of a lunch break), and I've still managed to be a productive little worker bee. I'm no Leonardo, but I'm a little surprised I'm not groggy. I'll still make an early evening of it tonight, I think, unless something ridiculous presents itself. As my father's fond of saying, "no rest for the wicked."
