Your description indicates that your son's level of impulsivity is a problem. It is the one aspect of ADHD that is most difficult to treat. Both hyperactivity and inattention respond pretty well, overall, to medication, but impulsivity often does not. He might benefit from a social problem-solving or social skills group. On your part, you might seek out some counseling to address the nature of your relationship with your son. As I'm sure you know, it's not a good development if you are finding it hard to like your son. Alienation of affection between a child and a parent is usually a precursors to major problems, so this is something to tackle.
Also, my son is on 70 mgs and having panic attacks. I just left her a message that he needs to go down on his dose too. He has hyperactivity.
I know what you're going thru.
