"i&#039;m 18 years old. i have been on adderall for about 3 years and it is amazing. i&#039;m adhd. i have tried vyvance which did nothing for me. i have also tried ritalin which caused a complete mood change. i had very depressing thoughts and a overall bad mood. the littlest things would set me off. i thought i was going to kill. adderall is what i found right for me.
