Interesting ! It is a key topic in nowadays' world, has always been anyway ; as for my experience, I've had my share of sleepless nights, as sometimes I'm so busy I forget sleeping :D But this never happens 2 times in a row, I guess everyone has different patterns but basically you should define yourself "relaxing periods" where you sleep more if you are used to working a lot just to prevent burnout issues
Thanks for commenting, @loonyfool! For me, my issue wasn't sleeplessness, but quite the opposite. I'm trying to teach myself to sleep less in a way that is sustainable. Have you ever tried mindfulness meditation? That helps me on the occasions I struggle to get to sleep! :)
I do it sometimes but not on purpose, just to relax, I can do it while listening to music songs then I remember some interesting things linked with it, things like that, I always enjoy linking a sound or a vision to a memory or to some other knowledge, it's like gymnastics for your own mind to do that kind of "linking" work :D
