"if you have adhd, pills like strattera (non-stimulant) do not seem to work. you do need a stimulant. concerta is amazing medication. i used to be on it from 2nd grade all the way until 9th. looking back now, at 21 years old, i see that after i stopped it in high school, my grades dropped. just started taking the average adult dose of 36mgs and it has really helped me in class, although there isn&#039;t an insane change. make sure to take it with a decent meal or immediately after. if you don&#039;t, you&#039;ll find yourself with an upset stomach for a lot of the day."
