I sleep 2-8:30am during the week, and 2-10am or so on the weekends. I could maybe try going to bed at 1am, but going to sleep before midnight usually results in being awake from 3-5am which is stressful if I feel I have to get up the next day. One interesting thing I've noticed, is that when I get 8+ hours of sleep, I'm happy but not as productive. On 6.5 hours of sleep, I'm a little grouchier but a LOT more productive. It's like I get into a mode where nothing feels right so I may as well just bang it out and get it done, whereas when I feel 100% mentally, I spend more time noodling and trying to find a better/perfect solution. I'm 40 years old and a software dev, btw.
