I used to work nights, 7pm to 7am. And, I know it throws your body off. Everything is kinda out of whack. I did it for 5 years, so I became adjusted but I think that might be why you feel like you are eating too much.
Someone mentioned that you should try to break up your meals and I think this is a great idea. Also, you need to be getting more fruits and veggies along with the extra protein. My trick for this is to cut up a bunch of veggies at the beginning of each week and put them into snack size baggies so I can just grab one as I'm running out the door.
If you make out your meal plan, then I think you will find yourself getting more balanced meals, and then you will start seeing those numbers drop.
Good luck!
