Welcome to the time change
It kinda sucks when you are already working your third twelve hour shift, actually this is my fifth day in a row... the first two were overtime. At least I don’t go back until Wednesday morning... a 3:15 a.m. wake up is miserable as well ...
I feel your pain
Good luck
Really hated it way back when I was a flight instructor and one week was an early shift and the next week was late shift. And continued throughout the year.
You just do what you have to, it kinda comes with the job...
