Even though I am not a night shift worker, I have chronic insomnia because I seem to have my days and nights backwards. I function during the day and I don’t take naps, however, I’m fatigued, somewhat sluggish and not motivated to do much of anything. Granted, I also have depression and these are symptoms of this illness, too, however, often I am much more alert at night, I have an incredible appetite (I don’t each much during the day) and my mind is much clearer. Most nights, I don’t go to bed until 2:30 or 3 a.m. Anyone else experience this?
