I finished my semester on Friday/Saturday at 1:13 AM. And then I was up at 8 am to hit the road for my parents house for the weekend. I've had about 6 hours in naps in the last 2 days and I'm still exhausted. I'll attribute that to staying up to midnight the last two weeks and then getting up at 6:30 am for work.
Yeah. That'll make you tired. But I'm optimistic - it's Christmas!
