My son is 8 and was put on Vyvanse a little over 3 months ago for his ADHD. He improved almost immediately at school and home. But the last two weeks he has been agressive, wont go to school, etc. He also says that when he is at school he "dreams" that I am dead and it scares him. I plan on taking him back to the doctor next week but thought maybe someone would be able to shed some light on this for me. Thank you :)
