Insomnia

I am a total zombie this morning. I went to bed about 10 or 10:30 last night - normal. But I woke up at 2:30 and I couldn't get back to sleep! That is so totally NOT normal. I tossed and turned until 3:30 and finally gave it up and turned on the light and read for a while. That got Tink awake and she wanted to eat and go outside. She must have figured it was morning. At about 4:30 I put the book down and gave sleep another try but no go. Couldn't shut off my brain ... there's just too much stuff going on right now. I have so much to do. The last time I looked at the clock it was 6 and I dozed for about 30 minutes until the alarm went off. I feel awful. I have to give an exam here at 9 am, then as soon as she's done I'm going to go shopping ONE LAST TIME - I swear!! - and then go home and take a nap. I hope.
