Another personal anecdote to support this; I’ve done this sort of “reset” more than once, and there is a qualitative difference between getting 9 hours of sleep between 10pm-7am and 1am-10am for me. Your mileage may vary, but that 3 hour shift is the difference between feeling like a winner or feeling like a loser for me. I don’t know if it is psychosomatic, but I also don’t care if it is as long as it keeps me feeling good.
