Not Sleeping

I'm really tired of not sleeping.  I'm tired or counting the chimes, hearing what time it is, and wondering how long I'll be in bed.  I know that I've read if I'm still asleep after half an hour I should get up.  But reasonably, I know I won't sleep when I'm up and I will obviously go to sleep in the bed so that is where I should be if I want to sleep.
Last night I went to bed about 11:30 and was still awake at two.  Then I had very vivid annoying dreams. Maybe tonight I'll sleep.
