Hey! Sorry for late reply, was at work. And definitely. It all depends on your mind, your ability to not give into peer pressure, but that all comes with why you’re being vegan anyways.
I’d transition slowly if i were you, plus meat and cheese are expensive anyways so you’ll probably consume it less than usual :) I became vegan in my third year of uni and it was absolutely fine, I wasn’t living in dorms though :)
