I used to, I am Austistic, so my mind does tend to wander.

I don't know if I ever technically had actual insomnia, but I can very much forget that I should be sleeping. And before I learned about alarm fatigue and cleaned up my alarms to a degree that my brain wouldn't reject, I would often end up staying up way past my sleep alarm going off.

But now I have a reasonably minimum amount of alarms only, and I am properly able to obey them without any resistance. When I get in bed, I start up my sleep music, specifically crafted to start at high energy and methodically wind down. By the end of the music I will have fallen asleep. They are all songs I have heard thousands of times, so it won't trigger fomo and keep me awake to hear the rest or anything.

I do not touch my phone again until I wake up in the morning, I don't have a morning alarm, as I don't need to be awake at any specific time, so I "sleep until full health" like a videogame character, except honestly I think it works to a degree in real life too. I'm never sick, and my injuries heal faster than other people's. My mind and body just have enough time to get done what they want to get done while everything is shut down.

I'm over 40 now, but still feel like a teenager.
