I've had insomnia since I was 12, and I'm almost 24 now. I can't even imagine what it must be like to constantly go through these terrible nightmares -- night after night. I totally understand the restless bit, though. A good night for me is 4 hours, so I feel you on being so drained and zombie-like. *hugs*

Hope Breaking Dawn is awesome and that you have a good time when you see it! :)
