Hey, 2 stage sleep works for me as well. Yes, being retired helps. I sleep through the night 2 or 3 times a week, but usually 3am I am up and reading for about an hour. I am still on a high dose prednisone slow taper, recovering from bout of GCA but the 2 stage sleep has been a thing even when I had weaned to 2 mg last year. I had been a night shift worker for 20+ years and relished sleeping in mornings.
