I’m the early days of the COVID lockdown - March and April of 2020, my partner and I ended up routinely staying up until two or three in the morning and sleeping well past noon. Eventually when I started taking classes and working again I realized I needed to un-fuck my sleep schedule and within a week I realized how terrible I felt all the time when I was doing most of my sleeping during the day. Even if you get a solid 8 hours, sleeping during waking hours will make you feel like absolute shit.
