Just to throw this in there:
I am not on any meds and my “normal” time to fall asleep is about 2 -3 am. I wait to go to bed until I get that “falling asleep in the chair” nod off going on.
I have always been a night owl, even way back in high school (I am 47 now).
I do watch YouTube in the living room as almost nightly routine though. Not sure it helps though.
I do find it easier that I be the last one up and awake.
Hope this helps or is at least an interesting point of view.
Good luck
