"i&#039;ve taken concerta on and off since i was 9 so 11 years now. i&#039;ve taken every adhd pill ever made and this one is by far the best out of them all. it has helped me a lot in life. i was able to focus in school and i always had good grades. if you miss a dose you can definitely feel it both mentally and physically.  i was able to graduate at the age of 16 and start working full time. i&#039;m not sure where i would be in life without this truly amazing pill. i would recommend to anyone who would benefit from it."
