Total rollercoaster. I had mono in the first half of my first year, so I lost about a stone in total just from that. Then I gained a few next semester. During second year, I lost a few kgs, then during exam period this year I gained another 2 kgs.
gained. mainly because i was in catered halls, so it was like an all you could eat buffet of not the healthiest food. however all came off straight away when i came home for summer. just lay off the fast food after the nights out & stick to low cal alcohol drinks, you should be okay.
I lost it because when left to my own devices I don't eat much. I'm too lazy to cook anything substantial. My appetite tends to plummet when I'm stressed as well, so that affected things, and because I moved to London I walked around a lot more.
