I do something like this once in a while. When I get sick of staying up late and sleeping in too many days in a row, I start going to bed about four hours later each night, and reset my schedule to normal within a week. This weekend has been a good time for it, with one less hour to get past. 28-Hour Day: https://xkcd.com/320/ https://xkcd.com/320/ What kind of latitude do you live at? I wonder if the schedule you're describing would be worse in the summer or in the winter.
