When I used to work the night shift as a nurse, I'd wake up between 3 and 4 in the afternoon, whether I went to bed at 8 or 11. It used to drive me nuts. I'm 13 hrs ahead of my normal time in Ohio so it's kind of like my body thinks I'm staying up[ all night working the night shift. I'll try to keep it detailed. Like I said in another comment, if not for the readers, for myself in the future.
