Hey Bren,
Strattera would be good to try if he really has to be on medication. However, I would suggest first trying some alternative treatments. I myself take beCalmd. It is all natural and has helped a lot of people who have ADD and other problems. You can buy it off the net. If you wanted to you could go to a vitamin store and get all the same ingrediants but the problem with that is he would have to take a lot more pills and it would probably cost more. I take beCalmd for ADHD and it has worked better than anything else for me. When I was younger I was on adderall and I recently did a breif trial with strattera. BeCalmd has helped me more than any medication has and I encourage you to try it for your son. It can take about one week to two months to notice positive changes. So, is your son in high school now? He should be able to recieve accomodations in class to help him out. Think about asking his teachers if he can bring a tape recorder to class and record all the lectures. Also he can request written copies of homework, lectures etc.
