The whole thinking of this is to reduce sleep time, I know, but what I find is that I hardly ever do anything of value after 10 PM, and if I do, I don't remember it very well the next day. So around 10:30 or 11:00 I go to bed, then I wake up around 6-7 AM, so that way I can get things done way before I go to work. This way, it allows for a more relaxed day and I usually get more things done when I get up early. I don't know what it is about waking up early, but it certainly boosts produectivity. Now if I could only get off these 2 PM to 10 PM shifts at my work...
It sounds like you're an 'early bird' as opposed to a 'night owl'
Everyone has their own circadian rhythm which dictates when they're sleepy and when they're awake, yours definately sounds like it has an early start so you're awake and alert early in the day and you start to flag in the later evening. I'm the exact opposite, I can make myself get out of bed by 6:30am but I'm a zombie for the next hour and my mornings are slow, however from about 8pm to midnight I'm at my most alert and creative.
If you're an early bird it's good to listen to your body clock, and it sounds like you're doing that which explains your good results. If you want to shave some more time off your sleeping hours you could try setting your alarm clock half to one hour earlier and seeing how you feel when you wake up - if you're more alert then you've woken up at the end of a REM cycle and it's a good time to get up, if you're groggy just go back to your usual waking time.
