Sleep Deprived

I've been back in Grand Rapids for a couple days now, and I haven't been able to get much sleep. It isn't from lack of trying, I'm just not able to fall asleep to have actual rest. I've slept maybe a total of four hours since Tuesday, and even as I type this I'm yawning uncontrollably, so I know I want to sleep-- I just can't seem to achieve what seems to be a really lofty goal. I really like sleep, as I have strange dreams that make no real sense most of the time.
