"my son was prescribed this medication for the second time.  2 years ago along with amphetamines while in kindergarten and he became very aggressive to the point he hit me, he had terrible anger outbursts, and a lot of issues at school.  but i was going through a divorce and 2 years later we decided to give it another chance in case it was more behavioral; however, after 2 weeks, i receive an email from his teacher about how his behavior changed dramatically for the worst. again we stop.  this time we know he&#039;s in a happy home environment and his behavior is much better so it became obvious it&#039;s the medication.  not for my son. he&#039;s on vyvanse only now and we&#039;ll see how that goes."
