:(
sucks
Im just yapping at this point but whatever. I also sometimes manage to fall asleep watching the most boring movies posible. Specially really old horror movies like from the 30's where there is just static black and white, the crispiest narrator voice barely understadable, a semblance of a plot, characters do be talking, what a about, that's the real mystery. Sometimes the brain just dips out of that.
Very dumb recommendation but Murder by Television (1935)
Peak of this. Zenith of boredom. No one's beat it since. Try it if you want. It's far from conventional method but living enough time with insomnia you learn to stick with whatever works and not question it much.
Hope you can catch some sleep soon <3
