I did this for two reasons: (1) I promised myself I'd get to Inbox Zero by the start of the New Year (and really, "tomorrow" doesn't start until you've slept, right?) and (2) I can't shake my adrenaline, but I need to rest, so I'm running the tank until it's empty and I crash (controlled, into a padded wall... in this case, my bed). I'm pretty sure I can convince myself that I am tired now.
*checks* Oh whoa. Yeah. I'm tired. Okay.
That is all.
