Day 1 and I can't stop thinking about food.

So I was wondering if this happens to anyone else, and if it will pass. I can't stop thinking about food. I am drinking water and I know that I will make it through today. My only problem is that every second I am thinking about food. I live in a Dorm and they have free meals, and I find myself rationalizing that I am losing money by not eating the meals provided. How I am missing Breakfast and Lunch ... I feel as if I am losing out. I don't know how to get over this line of thinking so any help would be great!
