I’ll just add a datapoint that nothing like that works for me. I’ve tried every ‘sleep hygiene’ regime, every technique etc. for 15 years or so after finishing University (and scraping through due to what I later realised was basically chronic sleep deprivation) and literally none of it helps a jot for me.
There’s so much going on with circadian rhythms and the difficulty of trying to go against your natural rhythm can be (in my experience) almost unbelievable to someone who hasn’t experienced having actual disorders in that area.
For some people it’s just not ‘knowing how to sleep’ or an issue with discipline, but for a decent number there’s actually deeper causes that are incredibly difficult to fight against (my sleep doctor literally advised me that I might have the best success in the long term moving somewhere where the culture is to wake later!).
