I believe in backlog.

I'm pretty much always tired. I wake up almost every morning still feeling sleepy. Even after a good night's sleep, I'm tired. Even after the very rare occasion of sleeping till noon, like I did this morning (wow!), I still wake up tired. Backlog, I tell you.

Getting a sufficient amount of sleep one night (or even several) does not seem to make up for the backlog of tiredness. That's my theory, anyway. Otherwise, why would I still be tired today?

Backlog. Gets me every time...
