This is very interesting.
Until I was in my mid-thirties, I had problems sleeping. On the whole, I sleep very well now. My technique is not anything that I could sum up as beautifully as you have.
That said, I am going to watch myself as I drift off ... I wonder ... do I do the things that you suggest?
Anyway, I have read posts here that indicate that many people have tilt-a-whirl brains and they are regularly sleep deprived. I hope they read this and that it works for them.
