I found a backdoor into my bed
https://trufflesecurity.com/blog/removing-jeff-bezos-from-my-bedI can relate, having suffered the same for most of my life. One thing that really helped me was a simple white noise machine, typically used to help babies sleep. Good: I sleep great with it. Also, it's not connected to the internet and doesn't require an app. Bad: I basically can't sleep without it. I have to travel with it (camping!). I even purchased a backup in case the primary fails, which has happened.
The other major sleep improvement was putting effort into accepting that life is pretty great; all of my worries that kept me awake at night were overblown. This took actual work, but it paid off.
Anyway, just thought I'd pass that along, hoping it might help someone else that struggles with sleep.
