My 15 year old son has been on adderall 20mg per day for the past 3 months. It has been super helpful in terms of his school day productivity. The side effects have been decreased appetite and difficulty getting to sleep. In the last few days he has barely touched food, has been complaining of no appetite the whole day. The only thing he wants to do is immerse himself in many hours of video gaming (where he is constantly stimulated and screams at the screen) and his ODD has become severe and abusive. Not sure if I should stop the medication, switch to a new one, or what else to do. There is so much tension between us as I try to enforce any rules, moderation or time-management. We are both getting to the end of our ropes. Any suggestions? Has anyone found something that works with a stubborn ADHD kid this age?
