By going through the learning process, doing what I could when I could, at 68 I now use meditation and gentle Yoga to rewire ease into my brain! It's the easiest way for me explain it. I am also being treated by a team, that also makes a difference. When I lay down now, I go right to following my breath, being aware of how it feels breathing in, doubling the count on my out breath. No pressure, simply following my breath.
Highly recommend "The Miracle of Mindfulness" by Thich Nhat Hahn. A book that transformed my life in the mid 90's.
It is easier for me to let go, relax and find ease. Next thing I know, it is morning and I wake refreshed.
