- Exercise, even if just 10min daily
- Sleep in a colder room
- Maybe is a lot of noise around you, and night is the time for your brain to work cleanly. Reduce it (I find this recently)
- Stop being worry about not get sleep. The more you worry, the less you get.
- If can, sleep when you feel it, get up when not. Not force to get sleep if you know you can't. I think this help to reset the clock. After a while things start to settle.
- Substances amplify what is wrong, maybe. I think is better to fix the macro stuff, the routine, and then maybe use something.
- Temperature control. I sleep with the AC set at 65, a fan and a BedJet device.
- Blue light control. I wear blue light blocking glasses at night time
- Wind down routine. I am careful not to exercise, watch exciting shows or do anything that raises my hearth rate at least an hour before bed.
- No alarm clock. I have found that when using an alarm clock I invariably get anxious about it going off.
Hope some of that helps.
What really helps is silicon earplugs (they warm up to body temperature and mold to fit, so comfortable I've forgotten to take them out until I'm half way to work) - a lot of my issues are I require silence to sleep and stay asleep and the modern world just isn't conducive to that at all.
Do you have a thick blanket then? Or are you just covered with a thin bed sheet while the air around you is 65 degrees F (18 degrees C)? That sounds like it would be freezing.
2) I can't sleep with few or no blankets anyway. I mean I could probably adjust to it over time, or if I'd hiked 20 miles that day I bet I could, but I certainly can't right now under ordinary circumstances.
I don't start to think a room's too cold for comfortable sleeping until it's under like 60F. My sleep gets worse if it's over about 68.
... so yeah, as a married guy with kids and a job, falling asleep is hell basically every night.
I also started taking 1mg melatonin an hour before I want to sleep. That works wonders for me.

... and, umm, mindfulness, I guess.
It's worth noting that many allergy meds (like diphenhydramine) are anticholinergic, but only ones which pass the blood-brain barrier are linked to cognitive decline. So newer allergy meds like cetirizine and loratadine are better.
