Ask HN: Recovered insomniacs of HN please give me some advice

I've always struggled to sleep. I remember hating bedtime as a kid because I could never sleep so I'd just lay there for hours every night bored out of my mind. I probably slept for about 5-6 hours on average as a kid so I was tired all the time, but on the weekends I'd get to go to bed later and sleep in to the afternoon which would give me a chance to catch back up on the sleep I lost in the week.

This pattern is still with me today. I'm always tired in the morning and early afternoon, but wide awake at night. It's getting to the point now where I probably sleep around 3-4 hours on average in the week then sleep for about 10 hours on the weekends because I get to sleep all afternoon.

I've tried all the typical stuff like "having a routine" and avoiding blue light exposure in the evening, but it seems to do next to nothing for me.

I feel like every year my insomnia gets a little worse and it's beginning to have a noticeable impact on my wellbeing and productivity at this point. For example, I'm beginning to struggle to tie sentences together and I find it hard to solve difficult technical problems.

I'm almost certain nothing anyone will say here will work, but I'm open to anything which might help me end this endless exhaustion. Ideally I'm looking for unusual suggestions because like I say, I've tired everything people typically suggest when it comes to good sleep hygiene.
