Work is a problem x2. There's the boredom/aggravation of being at work that makes me crave food. Then there is the "reward" switch of leaving work. The latter is easier to deal with. Once I get in the car I just program "Home" into my head and once I walk in the door the urge to grab a beverage or food product subsides.
But being at work is hard as I am bored to death here. This is not due to have nothing to do, but that it is the least stimulating job ever. I also eat 3 times faster at work then I do outside of it (which is saying something) because I get no designated breaktime. Still, my main binge eating is post work, so focus on what matters I suppose.
