Yes my ds is on Roaccutane. He has only been on the since July. He was only on 20mg, lowest dose. Went to 40mg for a week, constant nosebleeds at night, went back to 20. Joe says he wants to quit. 
I feel very differently to all of you re the drugs at Uni. I don't see it as a problem. It is, if you have a generally addictive personality, MH issues. In which case that is something that any parent would be working on : monitoring their child's well-being anyway. My 2 are so anti drugs, fitness fanatics, they get on my nerves as I sit down to watch Scarface, with a glass of wine and a family pack of crisps. They seem horrified that I tried a few spliffs at Uni. So I guess it's not a concern for which Uni my ds applies for. Don't most that aren't interested just not mix with those that do?
