What a topic! Well, I'm generally a night owl. My inner clock can get easily screwed up if I don't try to stick to a bedtime. I'm also a person who requires AT LEAST 8 hours of sleep. I'm probably a 9 hour sleeper by nature. I haven't had that in a few years. Right now I try to go to bed at 11pm but I admit if I'm working on a layout I lose track of time. Usually when my head hits the pillow my son wakes up for his feeding. Then he wakes up 4 or 5 hours later. Then right after my daughter wakes up and climbs into bed with me. Then my son wakes up for the day. So.... I THINK I sleep somewhere in there. I'm guessing I've been going on 4-5 hours of sleep for a REALLY LONG TIME!
