This is spot on. For me the key is in getting up earlier than ever you would need according to daily pressures. Right now I'm getting up around 4am, and since I adapted to it (I take melatonin so that's really easy) I don't need an alarm clock anymore. Sometimes I wake up naturally before that, sometimes later. But it's healthy, my body gets a gentle start, and I'm never late (on days I oversleep so hard that I feel sorry for myself it turns out it's 6:30am or something) if duty calls. And as a programmer I love getting some good work done on side projects before I head off to work my 9-to-5.<p>Granted I need to hit bed around 8pm at most (since I really like to get up even earlier around 3am), and I'm still trying to puzzle out how that's gonna work with my social life. My day job kinda gets in the way of otherwise being able to do a siesta and then sleep less at night. But for February I took the plunge of sleeping at the same time everyday, and that means a full month without nightlife, to cement a good habit. Carnival season 'round here makes that easier, since there is beer and parades a-plenty as early as morning.
