Sleepless on a Wednesday night...sigh

Finally, I'm catching up on sleep I lost on Wednesday night. For some reason, I only slept 4 hours, and I was up at 3:30 in the blessed morning...which is definitely NOT my normal hour of arising. I just couldn't get back to sleep, and I was pretty brain-dead for all of Thursday. It's a wonder how I stayed upright during the dance class that morning. I hadn't felt that sleep-deprived since my kids were little.
