Ritalin
Hi Justin - sorry to hear about the negative news.
My wife is a GR 1 teacher who I think has kept a couple of kids off Ritalin by firm, caring guidance, clear rules and the knowledge that some kids don't fit into the standard classrom environment as well as others, without necessarily being "damaged", just normal.
From what I've seen and heard, a lot of kids who do end up on Ritalin could be prime candidates to be good armed forces personnel. Maybe the recruitment policies should be reversed - if you've been on Ritalin, you're in!
Good luck with your goals.
