A very hyper day for me, too. I started by bouncing around on my tiptoes, involuntarily, at about three thirty this morning after only a about two hours of sleep. It was my second try at sleep for the night. I don't bite, I hit when there is need, whether it's from rage, frustration or lack of tactile sense. I have a punching bag for that. It helps a lot. I haven't broken the bones in my hands since I was a teen, but I've had a punching bag most of that time.
