Hi @shar1438
Have you tried yoga nidra practice, also known as yoga sleep? In addition to classes, I practice it on apps (Headspace and Insight Timer). It has been very helpful to me. Give it a try.

In conjunction with my other post above, today, I have a routine that helps but it is work at getting to sleep. While very soft classical music plays or the sound machine is set to waves crashing on shore I repeat a short soliloquy in my mind: “no thinking to resolve issues. Those thoughts that do arise are either deleted, deferred for daytime, or allowed to expand for pleasant feeling, now.” I then try to do that for each thought while further saying in mind: “allow sleep” until I’m relaxed. Finally, by the time I get to “…now sleeping…” I am drifting into some expanded story. It works more often than not but it is work. Candidly, this is a synopsis of a long story I read on a sleep forum many years ago. Maybe you can modify it to work for you.

I find that if I have lots of exercise during the day (walking, errands, chores at home, helping others etc) AND especially fresh air, then your body and mind will need rest and you will get that deep sleep you require. Courage!
Spring is in the air, even here in Canada! Let us count our blessings!
