"i was given strattera to treat my add. i began taking it with a free packet that ranged from 20mg to 80mg. at about 40 mg i began to notice that i was able to concentrate better in school. when i got to 80mg i began to not daydream anymore and people found it easier to talk to me because i wouldn&#039;t be constantly jumping from subject to subject. my anxiety and sleep problem was also solved. however, after forgetting to take it one day, i got a massive headache, equal to a migraine. besides that, i have had no other issues and it has made life much calmer and it has made my grades improve alot."
