>Most nights, I woke between 2am and 4am, tossed and turned for an hour

It's interesting that today this is very quickly framed as pathological, but in a lot of cultures biphasic sleep actually used to be common. A lot of preindustrial English language literature for example makes explicit references to "two sleeps". Many people used to sleep from around 9-11 pm, then engaged in various activities for one or two hours and continued to sleep. It kind of blew my mind when I heard about it the first time because of how completely this seems to have vanished, not just the practice itself but also discussion about it.

I think for people stressing a lot about sleep it's probably worth taking into account just how artificial the whole factory-job era on the clock sleep schedule is.
