I do the same. If you listen to the same one every night it helps you fall back asleep if you wake up too. Sort of Pavlovian

I’d definitely ask someone—I’m in birth control and various other medicines but have used, with doctor knowledge, both OTC melatonin and Rx melatonin, which both helped some, without affecting me the next day. That said, I recently got a medical marijuana card, and that’s been game changing. Idk what the laws are where you live, but I’d discuss it with someone if possible—I can’t remember the last time I got over 6 hours of sleep consistently, let alone any kind of sleep quality. I was resistant to trying it for a long time due to stigma and family attitudes, but I’m at a point where that stuff just doesn’t matter because I need sleep.
