Hi Steve - Whilst it seems at the moment you don't need to be up at 7, have you considered training yourself to get up at that time again, in readiness for going back to work?
I'm not a night owl. I've always been an early bird. It's rare I'm sleeping later that 07:00, with 05:45 being the routine 3 days a week, when my OH plays golf early.
I must admit, I quite like our routines. Being up bright and sharp makes the best of the day, in my view, but of course, we're all different.
