Insomnia

As far as I'm aware, I have little to no stress in my life right now. I'm in ONE, (count it, one) class, and I've got a bad habit of not doing the reading without any guilt. Work for the judge is interesting but not overwhelming. And Monday is a holiday.

So what's with the random insomnia?
Friday night, we had friends over for dinner and stayed up talking, playing video games, etc. 'til 3:30 AM. Unplanned, but a blast. Unfortunately, because of the early wake-up for the judge, I couldn't sleep in.

So, a few short hours ago, E & I crawled into bed after K's birthday dinner and fell into blissful, much-needed sleep.

Now, I'm up, completely awake, and exhausted. What the hell?
