I've had success taking sleep even further. It seems that humans are polyphasic sleepers, just like most other mammals. I've found that I get tired after lunch, and benefit greatly from a 30-60 minute nap. The trick to getting the most out of polyphasic sleep is having a bedroom conducive to quality sleep - it should be cool, very dark, and very quiet. I use some opaque shades (shift shades) to block the light from the windows, and either a white noise machine or fan to ensure I'm relatively undisturbed by sounds outside my room.
