I thought that my attempts were countless, but when I actually <i>had</i> to fix it due to a psychological disorder, persistence and body scan method made their job in just a week or so.<p>Also tried melatonin, mostly out of curiosity - it clearly sedates, but doesn’t make me sleep. Tried common recipes like food, light, bed regimes, exercise, etc. Didn’t make a notable difference. I think these are for people with a mild or a specific type of insomnia/lag or maybe with a completely unhealthy habit.<p>Right temperature helped, good air too. Less stress helped, specifically I learned to say “fuck all that” at the end of the workday and to not bring it home. Not moving in bed after finding a comfortable position helped. (If you have to, move very slowly, that doesn’t “reset” the process).<p>When I want to not revert to 3 am, I just don’t. Everyday a reminder reminds me to go sleep and I do. My rhythms align in a couple months, but hacks work as well.
