I'm impressed by your determination. A while back, I had a big paper deadline a week away and knew I didn’t have enough time to finish without sacrificing sleep. Rather than cutting my sleep short, I decided to stick with 7–8 hours of rest and instead lengthen my wake window. I worked out a schedule that gave me six nights of sleep across seven days. It meant waking up at stranger and stranger times as the week went…
I'm surprised to hear that that schedule worked well. Even if you woke feeling well-rested, what did you feel like towards the end of the day, at your normal/previous sleep time? Personally in that situation I would (and do) get plenty of sleep every night and then skip the final night. I find the fatigue from a lot of lost sleep normally doesn't hit me in full until the second day after, and the final-day panic is e…
So I tried a complete “cycle” of 28 hour days until I realigned with the normal day. Which happens to be the same thing GP did. LCM(24, 28) = 168 which is 7 days with 6 cycles. Roughly 19 hours waking and 9 hours sleeping. I did let myself sleep longer instead of holding to 7-8 hours like GP.
It definitely felt weird because my wife wasn’t on the schedule, but I didn’t feel super sleep deprived. I’m sure with multiple complete cycles you’d see more adverse effects, so it’s probably best to only do this very sparingly. Maybe napping during the wake period could alleviate issues.
