Have you tried afternoon naps to compensate? I remember reading this theory a while back that we sort of naturally switch to a different sleeping cycle over the course of our lives, where older people tend to stay awake at night and sleep during the day as a sort of evolved way to split shifts for camp defence during the tribal era. No idea if there's any solid data to back it up though.
