I don't work with food but i was obsessed by looking at it, cooking it for other people, smelling it, reading about it etc etc etc.
There seems to be 2 camps - the one i was in where i could just stare at food all day (without being tempted) or where the slightest image/smell/thought of food would drive you to eating!!
I hope you're not in the latter camp with your job!!
Try looking at it and seeing beyond the initial temptation, think of the fat and rubbish inside it and what would happen if you ate it - ie spreading more lardy substance around your waistline, making you fatter and more unhealthy!!
You need to find a strategy that keeps you sane honey....
Luv,
