As a young man I tried polyphasic sleep. Basically it’s having a very small “core” sleep period with scheduled naps. Based on the idea of military and sailors having compressed sleep schedules. I did it for the wrong reasons (wanted to be awake to play games… yikes younger me) but it did work after initial difficulty. Also, it solved my insomnia for a good while after I quit it. Insomnia later came back a number of years later but I still have positive effects from it, like less anxiety regarding attempting to sleep.
