I have an 18-year-old son who has been diagnosed with ADD, but he is very irregular about taking his vyvanse. I was even there when his psychiatrist told him he needed to take it every day. Recently he missed a dental appointment, got confused about what time his school was out for the holidays, etc. What can I do?? He still lives at home, but plans on going to college or university in the fall, since he will be graduating in May.
