I do pretty much all the non-medical stuff for sleep. Very dark, very cold, memory foam mattress and pillow, weighted blanket, brown noise machine, nasal rinse before bed to clear out sinuses as much as possible. I haven't had good results with supplements.
But even so those are all second-order effects (at least for me) compared to the biggies like lowering stress, keeping weight down, controlling light exposure, and making a habit of going to bed early.
every journey begins with an intention.
Good luck with your sleep journey!
I do all of that except the nose machine and the nasal rinse. I'm off and on with the weighted blanket, sometimes it's really helpful and sometimes it keeps me awake.
I had a weighted sleep mask for a while and should probably get a new one, that was really helpful.
