I've done them a few times... each time was different, so I don't really recommend doing it. Schrooms can be very unpredictable! But since you're still in college I can understand why you'd want to do them...
I would HIGHLY recommend that you do a bit of research on this excellent website:
Erowid
I always promote this site for these types of questions (I also sponsor it) because it is extremely informative and has EVERYTHING you'd want to know about every drugs on earth (legal or not) include tons of personal individual experiences from people who used these substances... plz take your time to visit this site!
And just watch yourself man, make sure you have some good/reliable freinds with you if you do decide to trip out...
