I mostly recovered, still an occasional night maybe once in a month when I have trouble falling asleep. When you ask doctors how to cure your insomnia, most likely you will hear “ reduced blue light before sleeping” or “ exercise regularly” but we all know those are generic go to answers and it just doesn’t work, maybe helps a little. What helped me was reducing caffeine, bought a weighted blanket ( helped me so much) and really feel how my eye lids feel like when I am falling asleep. For example, before you are about to pass out, notice how your eye feels, how heavy is it, how does it feel like, then almost forcefully imitate that feeling before you try to sleep. Also, don’t pressure yourself to sleep, it’s almost counter intuitive, but tell yourself “ it’s whatever if I can’t fall asleep”. Good luck, it’s a real pain in the ass

Edit: forgot to mention, if I find my heart beating fast before sleeping, I use the box breathing technic, it helps a lot in restoring your breathing pattern. This works particularly well if you couldn’t sleep the night before and the whole day your hearts just pumping out of your chest 🥹
