Sorry to hear it, Dan. This has been an issue for me for ~9 months. I wake up Every night b/n 1 and 4am. I’ve recently started using the Reverie app to help me get back to sleep. No, I’m not affiliated with them. They have a 7 day free trial. It worked, so I ponied up for the annual fee. After a few weeks, I’m getting back to sleep sometimes even without it. Good luck!
