I need to know the best method of taking our sons off of Concerta, both on 36 Mg. Our youngest son keeps an erection more than not. He is so out of control we can do nothing with him. The oldest son has problems also, but more social and anger aggression. We just received them from foster parents in on June 8. We have a new doc they will be seeing whom I hope will work with us in this area. I want to start over and see them without the meds and go from there.
