The ideal is waking up at 3am to do work? I can't think of many things that seem less like common sense than that. In the absence of an alarm or anything to wake me up sooner, I sleep straight through to the morning. I much prefer it that way, to be honest.
There's a term for it that I forget right now... morning sleep maybe? Second sleep?
Whether you call that time when you're awake "work" or not is irrelevant---I just meant that you're up doing something, even if its just reading or thinking or writing or whatever.
It seems counterintuitive but when you're properly rested, fit, and not using any real stimulatives/depressants, and you get in that rhythm, it works very well and comes naturally. Instead of 1 time per day of sleeping and waking up feeling great you get 3 times (pre-dawn, after dawn, then after your afternoon nap).
You just have to be able to do all 3 regularly to make it work, otherwise you skip a nap and you get screwed.
