I ran across this recently.....
How to trick your brain into falling asleep | Jim Donovan | TEDxYoungstown
https://www.ted.com/talks/jim_donovan_how_to_trick_your_brain_into_falling_asleep/transcript
It’s 12 minutes long and I found it helpful.
The best to you and hope it helps.
thank you for the link- another poster mentioned music too- I will listen to that tomorrow- (after a bad night’s sleep lol)- The problem with the folks is they wake up and their minds are all over the place- so hopefully that can help them calm the mind down-
