I hear you about the junk food temptations. I snagged some Taco Bell last week, after being tempted for much of Passover. What's odd is that I almost never eat Taco Bell any more, so I have no idea where the temptation came from. I snarfed down every morsel, then realized that yep, it was still Taco Bell. The craving was completely gone!
I'm not looking forward to going through badging when I begin working on site. It's going to be an awkward conversation, for sure, but hopefully my company's security will also have procedures for dealing with the situation.
