I too experienced all these things, no food, limited bathroom breaks. I hated the cell phone in my pocket going off when I was taking care of personal business. So I said forget this life is too short. I now work in utilization review. I miss the 3 days a week but I can eat, pee and make a phone call when I need too, no questions asked. I am still a nurse, make pretty good money (in fact, I make a little more because I work 40 hours instead of 36). It may not be for everybody but at 55 I can't do the floor anymore.
