Quieting my brain was a big issue on the first year or so - even today some circumstances get me bouncing around. I find if I engage in something that make me focus - a task of some sort - that helps.
Sometimes at night if I wake up I turn on some meditation music on youtube and listen on my head phones while lying in bed. Generally this will allow me to drift back off to sleep pretty quickly.
Thanks for the post - sharing what you go thru is very helpful to others.
Glad you're here
