I am so sorry to hear of your challenges with insomnia. At 79, I've been dealing with chronic insomnia for 50 years. Latest idea that helps is to listen to boring audio books on Audible. No offense to Mr. Churchill, but I'm finding his books on Marlborough and even World War II curiously (and delightfully) sleep-inducing. The voice actor who reads them has a beautiful baritone voice and plumey British accent. On some level, I suppose I'm absorbing a little history, which is good. (I am an English major, and somehow eluded all history courses. For the purpose of helping with insomnia, however, I recommend books in which one is not personally interested, lest one be kept awake attending to content.) Good luck!
