I've been up writing code at night since I got my first computer at 8, I'm 42 now, don't remember much about my schedule before then. Never could concentrate much during daytime, once my surroundings wake up my productivity goes down the drain. One thing that works pretty well for me when I'm allowed to set my own schedule is taking a 2-3h snooze in the afternoon/early evening. Then I can go on and work until 3-4am and still get up early without feeling like a zombie.
