My grandson has been on vyvance for about one year. He weighs 125; about 5'6" tall. He is in the 7th grade.
In the past three weeks, he has become some-what combative,practically. refusing to bathe, most times very compliant, I see this as a controll issue. What do you think? Any suggestions? Also, is there a limit to the time one should stay on the vyvance?
