This was actually a significant point of contention between myself and my advisor, who interpreted my working late at the lab as though I was trying to cram extra time to make up for not being there otherwise, or something. Those are just my most productive hours ¯\_(ツ)_/¯ but to him I was lazy and irresponsible.

My natural sleep period seems to be around 9 hours. I can make myself do 7 (I currently keep a ~1:30am-9am schedule, with some effort), but anything less has noticeable effects on my cognitive state, and I still start getting tired again around 5pm. If I do sleep at 5pm, I'll wake somewhere between 11pm and 2am, which is bad but in the other direction. So I have to fight through the late-afternoon slump. It's very easy to knock me off of this schedule, and I've been keeping it for two years since I left grad school.

Sleep disorders are real, and they are not simply symptoms of a poor work ethic.
