I can't emphasize enough what an impact this approach had for me. I suffered from sleep anxiety and insomnia. Took trazodone for years. It lost its potency and I wanted to get off the sleep drugs. Then I discovered history podcasts. The only ones that work have a single person talking and no ads intermixed with the podcast episode. Usually I'm asleep five minutes into the podcast. Then when I wake in the morning, I listen to it with my coffee. A few years ago my daughter was having similar problems and she too solved it with podcasts.
