oh, to finish answering your question - emotionally, you may get sick of school, want to go home, all that jazz, but that usually passes. Sexually, that's what you make it - you can go nail a new girl every night, or have a girlfriend, or be a loser. It's up to you. Physically, you'll most likely eat and/or drink more, so get to the gym a few times a week and run/bike/lift, whatever. College is what you make it - you can make a shitty situation better and you can make a good situation shitty. Just keep a positive attitude, make sure you go to all (or most) of your classes first semester, and get your studying in. May not be as fun as partying all of the time, but you don't wana be that kid who gets booted after one semester.
