My 6 yo son has been on Vyvase 40mg for 3 days now and although there has been a significant change in his focus and listening while at school and home, he seems EXTREMELY emotional. Like he is ready to cry at the drop of a hat and it takes a long time of coaxing to get him to even smile. Plus we've noticed that he has started doing this tongue rolling thing and it's not like he's even aware of it. Has anyone else's child experienced these same symptoms and if so, how long did it last for? He tried Medidate first but that had absolutely NO effect on him and then his doctor switched him to the Vyvanse but started him straight out at 40mg. I wonder if it's too much for him and a lower dose should be given to build up to.
