Hi there. I never took vyvanse for my ADHD but I have taken medication that has done that same thing to me. Does he eat with his medication? Also 70mg seems very high? I have had ADHD sense elementary school and the highest I have ever been on is 50mg and that was when it was sooo bad. I would research some other prescriptions for him to try. Now don't forget he's 16 and man boys can be badddd with temper at that age. My brother was like a demon child, :) lol It's puberty, girls, and appearance struggles at that age. Man growing up is hard. I would suggest trying Adderall XR or Concerta. Don't worry about the adderall getting out of hand it is monitored nowadays. You get it month by month. That is what I take and I asbolutely love it. With ADHD I found it hard to get up in the morning to have the drive for anything. I felt like school was a terrible thing and that my teachers absolutely hated me. It is all because they don't know. I would definately suggest encouraging him to write in a journal to just so he keeps track of things going through his head and doesn't get overwhelmed with 16 year old drama. I would def. think that's what is triggering his aggressiveness and also when my mom would pry at me whats wrong whats wrong when I was taking a medication that def. did not work for me. She got her head severly bit off. So I was the doer in this case not the taker. It's going to be hard for both of you with this. He is going to struggle through his whole life, but don't give up. You will find something. Also don't forget to bring his documentation to the school and see if there are any accomodations for him in school. It can be verryy frustrating and he could just be taking it out on you. (because your his mommy :)) When I went through my k-12th I had accomodations like private learning, note takers, the ability to record class and longer test times (even the ability to take home and go in private rooms). I would look into this stuff. If you don't have the documentation you need you can get the testing done in colleges, and at psychiatrists. Some are costly but some are free. (the free ones have a long wait list) But this will be very important in college, because it gets verryy difficult then because noone will slap you on the wrist when your doing bad or make sure your in class. They will jsut let you sleep in bed.

Im hear if you have any questions and I hope this all made sense.

Good luck!
