My ds is also adopted and was exposed to drugs and alcohol in utero. He has ADHD too. The difference between him on Vyvanse and not on it is incredible. You get to see the kid inside the kid. It is often hidden. Is it a cure all. No. We still have a lot of behavioral issues but at least we can work on them now because he is receptive. His body needs this drug. He knows he needs it too. Another advantage of the "label" is he is able to get classroom support and social skill lessons at school. He has some language issues that are also being addressed in the classrom. He would have nothing to help him without the label. So I'm perfectly fine with it.
