Anyone successfully reduced sleep hours per night?

Has anyone done this (and used a sleep log to document it)?

I've gone about two months sleeping 7.75h a night, but many of those nights I used modafinil.

Now that I've stopped using it, I sleep about 8.75h on average. Admittedly, maybe 1h of that is laziness.

I see sleep as a lot like food. We probably get 20% too much for optimal health/time management... but your body will always fight to keep you in homeostasis. Everytime I think I've managed to sleep less than 8h a night, I always end up catching up that sleep.

So what are your experiences?
