"i have identical twin boys that are eight years old. they were both diagnosed with adhd at a young age. at first we did everything possible to avoid medicines. after 1 year we started with adderall the extended and immediate release, 2 pills a day and were impressed. it&#039;s effectiveness was noticeable once the medicine wore off (moodiness, short temper,and rebound hyperactivity). after 2 years we were introduced to vyvanse and it is great. they only take one pill daily and it lasts 11-12 hours without the rebound side effects. the only problem is eating they don&#039;t have much of an appetite throughout the day."
