Well, first off, I wouldn't be eating cereal from a bowel. So many things that could go wrong with that!
That being said, I work nights myself. All I do is treat my day like someone who works days does.
Wake up at 3pm, have breakfast. Bring food to work to take care of lunch and dinner. More small snacks than big meals really. And when I get home at 715am, go to bed.
I have never believed in the whole breakfast in the morning, lunch in afternoon, dinner at night.
Eat how you normally would working a day shift.
That's just me though
