@jhpot As a nurse who used to work nights I had to re-adjust when I retired to a more 'normal' routine. I do some work outside during the day, I read for an hour before trying to sleep, I always go to bed at 11pm and set the alarm to get up at 8.30am. Sometimes I don't sleep well, but I stick to the routine as much as possible, or have ovaltine if I'm still awake at 3am. Mentally I go through every tiny step of making a complex garment or packing for hols to get me off to sleep.
