Stimulant side effects

My husband was diagnosed almost three years ago.  He went through different stimulants which did not work particularly well for him then on a higher dose of one of them he seemed to suffer some nerve damage.  One side of his face went numb and has not entirely recovered 2 years later.  He has been on Strattera since.  He says he has felt a little more in control at work, but at home I don't know if the meds are that effective.  He is still twitchy and constantly looking for stuff to do (everything but face our marital problems).  What other medications are out there?  I believe that he needs the talking therapy part of treatment and think that he may also be autistic, but he will not go to therapy willingly and seems to be resisting seeking another diagnosis.  Any suggestions please?
