I believe Wellbutrin takes 4-6 weeks to see full effects — ask the prescribing doctor.
I challenge you to try to see things from his perspective. Analyze the way you talk to him. Our kids with ADHD are very sensitive — if he feels any judgement (if if you don’t intend it), he will lash out.
He isn’t disrespecting you on purpose. He does care about doing well and meeting expectations.
He’s at the age where he wants to have some independence and making decisions about himself. Set guidelines for contentious subjects, like video games. Ask him how he’s feeling. Validate his feelings and show empathy. Ask, “How can I help you?” You’ll be amazed at how much this improves things.
