that used to be my sleep rotation - but these days it's left side to right side repeat and repeat about 40-50 times per night.
I got a weighted blanket for Christmas... (don't ask me why)... which is supposed to solve many sleep problems... it didn't. I don't mind it, it just didn't change anything for me except it IS very warm.
The only absolute 'must' for me when it comes to sleep is leg separation when I'm on my side, which I always am... I use a body pillow. During my backpacking days this was a huge issue... I'd fold my coat and use that but it wasn't quite big enough. My backpack itself I couldn't get into my sleeping bag. I actually started carrying a large body pillow CASE that I would stuff with leaves, mostly pine needles, and that worked pretty well but wasn't all that comfortable.
