You know how I can tell I need sleep? Because I lose all patience. That's always the first thing to go.
Part of it is my lack of self-control. I think I'm getting ready for bed early, and I hop on the internet really quickly and next thing I know an hour has gone by. Or I'm staying out late doing things with friends.
But part of it is that I am having trouble sleeping. If I do make it to bed early, I can't fall asleep. And on the rare occassions when I can sleep in, I wake up at my normal time.
It's not like I'm not getting any sleep. I'm getting 5 to 6 hours a night. But I would really like to be getting closer to 7. And I take a 20 minute nap most days on my lunch hour.
Maybe tonight I'll get to bed earlier. We'll just have to see.
