In around 2017-2018 I was dealing with insomina by using split sleep. Sleep five or six hours, get up, do some paperwork, go back to sleep for another 2-3 hours.
I stopped doing it, but this year I've had several nights when I couldn't sleep and I've decided to stop worrying about getting continuous sleep, except that now I seem to be doing 3am - 4am paperwork etc.
That would be fine if I were sleeping properly before that. I do some puzzles, try to sleep, can't sleep, do some puzzles etc.
I've just had a very productive planning and organising session, but I didn't sleep much before. I still need to crack the sleep thing. But I think that at least if I stop worrying about sleeping all through the night, I'm in with a better chance.
What I think I'll try next is what I think of as 'really early night', which could be as early as 9pm and certainly no later than 11pm. As someone who, over the years, repeatedly drifts towards a 2am lights out, that's early.
Anyway, I'll see how it goes, but if any of you have any 'odd' or 'interesting' sleep habits or know of them, I'm interested. Stuff the standard, I need to see what actually works for me.
