I don't know what you would call me. I am at my best with about 6 hours sleep. I would often get to bed at 1 am and be up at 7 am. I don't like getting up real early (before 6) but I don't like going to bed early either. I always wake up in a very good mood (I was called "chipper" this morning at swimming.) It is as the day goes on and someone is rude or snarls at me that my mood starts to change. But if I am annoyed with someone or something I will not take it out on anyone else - hard to do sometimes. I think people who do not wake up "chipper" would really hate me in the morning.
