I'm not sure why, but I haven't been able to keep my eyes open today. When I haven't been taking care of little chores around the house, I've been napping on and off all day. Now it's a little after 8:00 pm and I am thinking about making it an early night. Perhaps I am just catching up on the rest I missed over the past few months. I don't think it's anything to be alarmed about at this point. It's just been a sleepy day.
