My go to to get me off to sleep is listening to asmr - auto sensory meridian response.
As explained on another thread, if you have ever experienced soothing "tingles" over your scalp and down your spine from the timbre of someone's voice or a head massage asmr might be worth a go Quietlife.
You have to find the right asmr artist, as they're called, to listen to, as there's a lot of very weird & irritating stuff out there but it's such a help to soothe you off to sleep if it works for you. (Think a soft spoken Joanna Lumley or the late Una Stubbs).
One of the best for me, almost guaranteed to send me drifting off without pills, is a youtube channel called "southernasmr".
Hope you find my suggesting asmr useful as there's nothing more miserable and draining than chasing sleep & it does seem to help hundreds of thousands world wide to judge by the comments.
