Nutrition and Health

I am currently a Freshman in college, so of course it was a big transition to being around fast food places all the time. I would be up at all hours of the night studying or trying to finish homework and the fast food places were so close to me and so easy to get too. I am currently on break and I live far away from any fast food places but when I go back to school it's going to be really hard to resist going out to fast food places a lot, and keep on my healthy eating. I need some help on what to do when I go back to school.
