"My son was 7 when he started taking Adderall for his Aspergers Syndrome.  He was overweight but after taking the medication for 1.5 years, lost a lot of weight.  He is not a picky eater but his appetite was non-existent.  There was nothing I could do to get him to eat.  We did have to change his medicines and he has since put some weight back on.

The medicine did do for us what we needed it to do which was help with his impulsivity."
