I was skinny as f*ck working overnights at CVS. The week on was spent on strictly eat, sleep, work, repeat. Multiply by 7. As soon as I came home at 6 or 7 am, I went right to bed, and didn't wake up until 5 or 6 in the evening, only to do it again. There was no life for me during the work week. No time for family, hobbies. I did exercise and go to the gym in the morning after work, but if my friend didn't go with me, I became lazy. It was very difficult to sleep during the day if my family was making noise in the house or we had people over. Also, need black out curtains in the room.
I felt like a zombie working overnights. It wasn't actually during the night, but usually the next week, especially my first few days back into daytime hours, things felt surreal, or slow, or fast, or I don't know. The best way to describe it is like I felt like I was a human, but didn't fit in with the world because my life was opposite of what everyone else was doing, and the adjustment during the off week was hard to do, and it caught up the more and more I did it.
BUT, if I get the opportunity to do nights again in a hospital with a 7 on 7 off shift, I am going to take it.
