Naps on the couch are great. Sleeping next to my wife with our dog at our feet is heaven. btw we put the tv on low volume with an old movie playing and set the sleep timer for an hour or so, works better than any sleep pill.
When I first retired in 2003, I got used to taking short naps on the couch. Then I realized I felt worse when I woke up, so stopped the naps. I'm a woman, almost 78, take no naps at all. I stay up until 4 or 5 in the morning, and sleep until around 11. I always get at least 8 hours of uninterrupted sleep every night. I worked 3-11 most of my career, so got used to staying up later when I got home.
