In my ongoing quest to reduce fatigue and get more done, I've been looking into changing my sleep schedule -- as a freelancer, I have some options. I keep reading that it's more natural for most creatures to sleep twice a day instead of getting all their sleep in at once, so I tried to replicate the bi-phasic "siesta" schedule that moves a chunk of the total snooze time into the early afternoon. Didn't work for me, because I got too groggy long before the siesta time. Today I tried getting most of my sleep in one shot, waking up and puttering around for a couple hours, then going back to sleep for another 1.5 hours. This worked better, but still isn't ideal; I think I need a shorter wakefulness period and slightly longer "second sleep." It's hard to know whether something's working or not because of the inevitable "jet lag" of the initial adjustment period.... Anybody else running on an unconventional sleep cycle? What works for you?
