Vampire. I like my bed, especially in the morning. I've been like that since I was a small kid. Other kids would talk about watching Saturday morning cartoons and I'd always sleep through them. If I could work noon-8 I would but life ain't like that. Probably go to bed most nights around 1 am, fall asleep by 2. Up by 7 during the week. Depending on how well I've treated the wife during the week, she lets me sleep as late as 11 on the weekend. She on the other hand is an early to bed, early to rise type. Blech.
Working in a restaurant/bar for eight years did nothing to help. I'd start work at 4, finish at 2 and then we'd go out and party. I remember many times coming in the door as my dad was going out to work. I'd get up around 2-3. Oh, those were glorious days.
