If you are healthy, being physical I should think would be wonderful for you. To me, that would be a good way to make yourself good and tired so you can sleep. I do this myself. If in a bad mood, I do yard work outside, even sitting on my butt. If anxious, paint a floor..... whatever I can do to ease being jittery.
At night going to bed with a book, real tired.... well drifting off happens for the most part easily. I think being physical is good for any of us that can get around OK.. Keep on trucking and having hope. ginnie
