Since I had the luxury, I did something that I want to wholeheartedly recommend to anyone who can: I stopped using an alarm clock.
I'm a "night owl". I tend to have trouble sleeping before midnight, and often stay up later than that. Unfortunately, for most of my life (from school, to university, to a 9-5 job at a "real" company) I've had to wake up earlier than I would otherwise, normally around 7:00 or 7:30. It was always a struggle, and I would usually hit snooze a few times before I actually managed to struggle out of bed. Even if I happened to go to bed early enough to get 8 hours' sleep, I'd have trouble getting up.
It took me about a month at to sleep off my debt. Now I go to bed when I want, and wake up in the morning around 8:00 or 8:30, no alarm needed. I went from 3-4 cups of coffee per day to 1. I'm almost always in a good mood, even first thing in the morning. I used to be convinced that sleeping for 10 hours if I wasn't interrupted was just a fact of my existence; now I wake up after 7 and a half hours, all by myself.
This is not an endorsement for setting your schedule to 10-6. It's an endorsement for not setting your schedule. If you treat yourself right, body will know when it's time to get some work done, no clock needed.
