I work law enforcement and part of my job is working overtime. This is not a desk or patrol job, I am on my feet most of the day. With my first pregnancy I didn't get ordered to any overtime and I had a desk detail. This time around I have been ordered to work 16 hours quite a bit. I might add that I am also still nursing my 14 month old mornings and nights so I have to pump when I get ordered to work an extra 8 hours. Would you be really tired or are you tired working 16 hour days?
