The best most productive schedule I've ever been on usually came about around finals time in college.
I would wake up around 8AM, then fall asleep at 4PM, wake up again at 8PM and fall asleep again at 4AM. I was awake during all the necessary "business hours" to go to school, but I also had 8 uninterrupted hours in the middle of the night to study or read or whatever.
The best part was, whenever 4 came around I would get tired and fall asleep very rapidly, and snap awake fully energized at 8. Since I was never awake more than 8 hours at a stretch I was always refreshed right up to the time I would fall asleep. Meanwhile, unlike the hoax uberman or other sleep schedules, I was getting a full 8 hours of quality sleep per day, so I was never tired.
