"i started taking strattera in 8th grade when i had a low c in maths. i haven&#039;t had anything under a b since and i am now a freshman in college. it definitely worked for me, helps me focus. when i don&#039;t take it i do notice a difference in how i&#039;m feeling. i would recommend not taking it before bed, whenever i do i have nightmares and have trouble staying asleep."
