I have been working the night shift for 3 years now. I have no problems at work with being tired, I get sleepy occasionally when I have a good group of patients, but usually am fine at work. It us my days off that are the problem. Not just the first day. Some weeks I can function like a normal person, but other weeks I feel like I could nap all day and still sleep at night - well most of the time. There are other weeks that I am awake half the night, but not always. My schedule is so messed up. Anyone else with these bizarre sleep patterns?
