Can't sleep

I find that no matter how much reading and work I do in my solarium each evening I will have trouble falling asleep. I know I have more than the usual amount of stress and worries these days sitting in the front of my mind. You know, tax season, life, etc. The only way I can fall asleep is by reading for about 20-30 minutes. But if I start reading before I even feel tired, I never get tired. It's a new strange progression. I also find myself drawn to wandering about the home late at night gazing out the windows. There's nothing to see. There never is. But I am compelled to do so. I hope I can work this out soon otherwise this will be a rough tax season of 6 day weeks and not enough rest.
