I've always felt better when I got under 8 hours of sleep, so about a month ago I decided to take up a biphasic sleep schedule and it has been working very well for me. I get much more vivid dreams (and even remember most of them) and even got a few lucid dreams. I feel just as good as when I was on a monophasic schedule, and I don't need to sleep as long (a total range of 5 and a half to 6 and a half hours).
Unfortunately, the society I live in still operates on a monophasic schedule, so it's difficult when I have class/work whenever I'm supposed to take my nap and I can't delay it because my housemates all sleep around the same time. I still recommend everyone to try a different sleep schedule for at least a week or so.
I may eventually try the Everyman cycle and see how it works out for me. An extra 2-3 hours of awake time per day doesn't sound bad at all!
