This is simple advice, but was effective for me after some practice. For months, I had to fall asleep listening to podcasts because my brain would be thinking about work. I just couldn't shut it off. I decided I couldn't live that way, so I worked on breathing techniques like this. After a couple of weeks, I could finally focus on breathing long enough to fall asleep. I still have nights where it just doesn't work, but it's made a big difference in my life.
