I've definitely had sleep issues most my life, which I now contribute to this ADHD crap. Lately I've been doing pretty well on the sleep. I try to stick to routine and simplicity, exercise, diet and meditation, meditation doesn't have to be sitting in the lotus position, it can be working on a hobby, walking meditations or anything that draws your focus and attention.
My room is for sleeping, I have no TV, my phone is put out of reach and if I just can't sleep or I wake up and can't go back I get up and do something or start reading.
Chamomile tea is helpful sometimes
Only thing stressing me out right now is my truck project, I'm tired of working on it and want my weekends back.
Don't forget to check in on your people, let them know you're there. Talking to a friend just yesterday and she had to go pick up the .40 cal handgun her brother used last year to commit suicide, she said she won't ever open the box and will probably let her son take it and store it away, still has 4 rounds in it.
