My 11 year old was officially diagnosed with ADHD last week and was put on Vyvanse (30 mg). Since starting the medication, he has had terrible nausea and is not able to eat all day (until later evening). He is complaining about having to take the medication because he feels so awful, but I keep telling him that the nausea will go away? I have also noticed that he is incredibly grouchy in the evenings....is this a side effect that others have experienced? Thanks!
