I have slept many nights, on average about once a day for many years. In my experience, it's the routine that has the most effect. I know it's super difficult to maintain but going to bed and waking up same time everyday is the key.

Seems to be so, it hasn't worked for me in sometime.
First book I'm certain that I read front-to-back was the first HP book when I was 16.
