Sleep last night was not so great. I didn't drift off til about 12. I slept between 12 and 2, and 2 and 3, and 3 and 5:30, and dozed from 5:30 to 6:30, after convincing myself that no, really, the clock said 5:30, I could go back to sleep for an hour.

I'm armed with caffiene, and I'm not afraid to use it.

And now, I'm off to teach. I hope they're less groggy than I am today, or it's going to be a slow class.
