@cmd: Hi…. after 2 shoulder surgeries, and 2 knee surgeries, one of those a TKR, over the past 15 years (nicely spaced, of course), I am just grateful not to be in pain at night. Granted, I’d love to sleep more, and more consistently, but compared to the post-surgery months I take what I can get. The more I worry about not falling asleep, the worse it usually gets. I do always keep a book or 2 around as a sleep aid. The content must be interesting enough to make me want to read it, and boring enough that I fade out after 5 to 10 pages. It often does the trick.
