Getting to sleep at night has never been one of my talents. As a kid, fears kept me awake. As a teenager, I found the night the most intense time and didn’t understand why one was supposed to sleep during it. As an adult… if it wasn’t one thing that kept me awake at night, it was another.
Just recently I’ve been on a new regimen, and it’s actually working. There are three things I’ve been doing differently, and I’ve been sleeping with little or no trouble most nights. As for why I made these three changes, it did not come from any conscious decision but, apparently, from something on a subconscious level, some push for greater purity, a byproduct of which has been successful sleep.
I should add that if exercise is not one of the three things, it’s not because I don’t practice it but because I’ve already been practicing it for decades. I find it indispensable to decent mental and physical functioning. No, by itself it did not solve my sleep problem; but without it I wouldn’t have slept at all.
