headache

I woke up with a terrible headache today, and it pretty much took all day to get to the point where I could actually get something done. I'm still feeling it, but not nearly as bad as I was before. I know that I got it because of the lack of sleep I've had the past couple of nights. When I stay up too late, I tend to get headaches easier. I'm trying to learn the things that set off my headaches so I don't get them, but it's hard to always go to bed at a descent time. This headache has just been miserable for me because it makes me feel very sick. I'm praying that as the night goes on I begin to feel better.
