For those of you who have or had your difficult children on Concerta what do you think of it? psychiatrist is considering adding it to difficult child's medications. We go back to see her on the 25th, and she is going to go over the teachers questionnaires, and have us fill out one as well, but thinks it may help. How long before it starts to kick in? And, how long in the morning before you see it start to work? Just general ?s. Thanks everyone.
