I have an 11yr old son,high functioning ASD,ADD, and anxiety. We had a pretty Good year this year and saw an overall decrease in disruptive behavior. However, we still struggle a lot with attention span. Dr recently started out son on Quillivant xr. I wanted to try it during the summer to see if there is any benefit. Does anyone have experience with this medication? Our son is also on guanfacine and citalopram.
