I think the worse part of this is when we actually see some progress in the A and 'hope' that the nightmare might actually be over...then to find it's not. I hope your son really is on the right track, but from experience I have learned if they don't change the lifestyle and the friends they use (used) with. It usually isn't long before they end up back in the fray. I do hope that isn't the case with your son, but it's best if you set the boundary's you can live with now, it's your right to do so and not his right to steal your peace and joy from life.
