Have you tried a little bit of caffeine in the morning like 9 and split your work and then one nighttime comes do stuff that makes you sleepy! Definitely no phone or computer, you have to disengage yourself from electronics and try listening to something not metal like I do! And try reading to get you sleepy and trying to go to bed by 10 or 11 and try not to take naps during the day. Hope this helps a little, I have a different problem I stay up wicked late and wake up after five hours of sleep and I'm up for the day and I also take sleep meds. Hope it evens out for you soon

When I can’t sleep I get up. I do something until my eyes feel tired. Staying in bed with insomnia is the worst. I try to stretch or read or use duolingo— that’s last because of avoiding screens Sometimes getting up and organizing my drawers and stuff also helps I get to feel all productive and hours go by Sunlight first thing, like get up at a certain time get fifteen minutes of sunlight and if it still sucks go back to sleep
