When I can’t sleep, I turn around and sleep “upside down” - moving my pillows to where my feet were beforehand, and my feet to where my head was beforehand - and I stick with that for a week or so. It gives me a week or so without insomnia and then wears off, so I have to turn myself back around for the next 7-12 day period.
Admittedly this could just be a me thing, but let’s put our faith in this method and let the power of placebo effect take hold. Boom, minor bouts of sleeplessness are cured.
What are your own examples of this?
Idk how much it would help you, but if you can source some fairly common stuff and do some mild DIY, you can make a cold pack/pad that “freezes” at room temp and lasts a super long time. It isn’t cold, more like cool water that stays cool. You could even make socks out of it, if you want. They would be weird and squishy and probably trigger some sort of sensory thing, but you COULD :p
