My son is 8 in 3 months and has been on 5mg of dex for the last 2 years to treat his ADHD (he is supposed to take a higher dosage but I am afraid to give him more because I only want him to hae enough to concentrate at school) his doctor in the last 3 sessions has talked me into my son starting Vyvanse, I am going to start him on Saturday to see for myself how he reacts to this drug (I only medicate for school mon-fri) I am curious of other parents and children's experiences on vyvanse, I am scared of long term health issues and the depression or "sad" feelings I am reading about, I just need someone who has seen it first hand to give me their story, please help
