Between my prior position as a lab tech and my first few years as a nurse, I worked night shift for 12 years. I thought I had always handled the night hours well both physically and emotionally. I did, however, spend much of the first day off asleep - or just stay awake for over 24 hours and go to bed at night. I really, REALLY dreaded the loss of shift differential upon going to days. It was a significant amount, when you thought of it as a yearly sum. So I timed my change just as we got a raise. It didn't "hurt" as bad that way. Having a more "normal" life and circadian rhythm has made a tremendous difference. It's affected everything about me - social, physical, and emotional aspects, positively. And unless you have already "capped out" and are at your top wage for your position, you will eventually regain that loss of shift differential.
