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.
