I'm in college too! I actually lost most of my weight my freshman year when I was not accustomed to the dining hall and ate mostly rice/lettuce/hummus. I second(or third, fourth fifth???) everyone who says take advantage of your school's gym/rec center! It totally helps. If you can, minimize eating in the dining hall cause once I discovered the pizza, I was gone! Try to limit eating out with friends too, I know it's hard, but you can do it! Being a student, you have the built-in excuse of being poor.
As for alcohol, I am pretty atypical because when I lost the most weight I was drinking the most(2-3 times week...hey I was a freshman!), but if you want to drink use low-calories mixers and I usually avoid beer, it makes me bloat-y and funny feeling. But I am no expert, I still have tons of weight to lose! Good luck!!!!
