I wasn't sure what you had in mind as far as transitioning back to working days. It's been many years... decades really... since I worked nights. But I did. Actually I quite liked it at the time. I've always been sort-of a night person anyway.

For the most part, things were quiet on the night shift. None of the bosses were around & there were typically no visitors. (I worked in 3 different hospitals for periods of time.) It was just a slower, calmer pace all the way around (unless there was an emergency, of course.) At one of the places I worked we would often order out & have pizza or sub sandwiches for "lunch" at 12 or 1 a.m. I did also work days though at other times. It was much more stressful, in general.

I also sometimes had occasion to switch from working nights to working evenings or days for periods of time. Generally I would, as I recall, have a day or two off in between. I can dimly recall having done a few double shifts now-&-then as well though. But that was the exception rather than the rule. One time, when I had worked an evening shift followed by a night shift, as I was driving home in the morning, I fell asleep at the wheel & drove my car into a concrete post alongside the road!

Anyway... I would think the thing to do, as far as transitioning from nights to days would perhaps be to arrange it so that you have a few days off in between, if you can, so that you can get used to your new schedule. And then just realize that, depending on your work situation, you may find working days to be a whole different animal.
