I just took my 9pm and I feel pretty good, but not 100% - just like usual. I don't think that oversleep really affected my progress much.
I did make the Overkill Alarm Clock (tm) - It's a laptop that does nothing but run a cool alarm clock program. It's hooked up to a separate stereo system with a speaker on each side of the bed. I've preprogrammed all of my waking up times, so I don't even need to remember.
Hung out with Manish and Neetu and they are doing well too. We're all going downtown now to help stay awake. I feel like tomorrow or the next day may be when it finally snaps into place and I feel as good or better as when I was sleeping normally.
Every cycle has a rhythm to it, its own cycle. When I wake from a early morning nap (midnight - 7am) I usually start out a little tired, still wanting for sleep. That inevitably passes if I get up and start engaging my brain in something trivial like washing dishes or watching a tv show. Alertness follows for anywhere from 10 minutes to 3 hours. Eventually it comes back down, leading me back to sleep.
The sleep has its own cycle, from lying down to mental chatter, to unknowingly falling asleep, to deep dreaming, to non-REM unconsciousness, to gentle awakening. An alarm clock can interrupt anywhere in the middle of this, dictating the flow of the next waking cycle.
With the knowing that the tired feeling will pass if I just start moving, I now feel it's much easier to get up. I avoid productive work until the tired feeling is gone and replaced with alertness.
I always have trouble getting out of bed in the morning. I don't mind waking up at 4 am or 5 am because once you start moving around you feel less tired. The problem that I always have is waking up. I absolutely hate the feeling of waking up, I'm sure everyone knows exactly the feeling I'm talking about. Your eyes are heavy, you feel like a rock, you start arguing with yourself, and once you do that, you're never getting out of bed. The initial resistance is what keeps me from waking up early in the morning.
Designing a "good" alarm clock is a very tricky thing. Most alarm clocks are loaded with fancy features but in the end only done one thing right (and sometimes that even goes horribly wrong); blast a sound at a certain time.
To design a proper alarm clock, one would have to look at the issue of waking up. Which isn't an easy problem to solve.
I've recently stumbled upon a fantastic iPhone alarm clock app. It's called "Wake N Shake"
