Has anyone's child tried Vyvanse? If so can you tell me what you think of it? My 9 yr. is currently on 54mg concerta and i don't like it or at least it doesn't suit him well. I would like to find something else with a lower dose. He has tried adderall but that didnt work well either. He was on concerta 36mg for a year it worked great until he seemed to become immune to it or something. His school teacher called me up one day( a couple of weeks ago) and told me she can't get him to stay in his seat and he was playing with anything he could get his hands on.So thats how he got to the 54 mg of concerta. It seems to me even though its a higher dose his behavior has worsened. I dislike giving him high doses of anything anyways.There must be something else he can try. He has an appointment with his doctor tuesday and i thought about asking him about Vyvanse. So if anyone has tried it please tell me what you think. Thank you for your time.
