I noticed that I have all of this bonus time in the day and night, since I have full use of my brain (not drinking beer or wine at night, then recovering the next day in a fog doing the bare minimum required of me, repeat cycle).
I notice that I have an enthusiasm for the boring chores that I didn't get around to before, and I sometimes do them gladly. I notice that time goes by more slowly at night, and for now that is not a bad thing. So much to do!
