> The best change I made to my sleeping patterns is getting rid of an alarm clock. Get as much sleep as you need and then just wake up. I highly second that sentiment. I haven't used an alarm clock for workdays for years. (I will for exceptions like an early flight or doctor appointment or something.) About once a week, I won't wake up until 45 to 60 minutes past the usual time. If that happens, it was necessary, and a blaring alarm clock would have left me zombied for most of the day. I do have a fairly flexible work schedule, arriving any time up to about 10:30 is okay, and my manager does the same. This is by design not luck, I wouldn't take a job where that was not true. Biphasic sleeping seems to be my most natural schedule too, on weekends and the last time I was between jobs. Problem is that I end up taking a 3-4 hour nap in addition to the usual 7-8 hours at night, which really cuts down on available conscious hours. I'm undecided whether that's my most productive schedule, or whether it's best to avoid the urge to nap.
