Hi Maggie. My name is Michelle Hernandez and I am a police Sergeant also!!! I was on the grueling 12 hour night shift, but recently got transferred to Special Operations (which not only has my favorite, MOTORS, but is DAYZZZZ). I couldn’t stand nights and was sick basically the entire time. Some people have no issues, but I’m not really a young buck anymore. I did not have a problem following tailored meal plans at work, my problem was my off days, because my eating times were always so different than the days I worked. And our Agency does not allow working out on duty so on my 12.25 hour shift days, I rarely had any time to work out. I hope your Department allows you to workout on duty. It would have definitely made my life WAY EASIER. Best of luck to you:)
