"i am currently a junior in high school on concerta going onto 4 years with it and i can honestly say it does work very well. it helps me focus a lot and you can see the results inflicted on my academics and how good they got. but the side effects are the down fall of course. i get insomnia and i lose my appetite completely for a whole day. and on top of that i feel emotionless, like a robot that all it wants to do is study and focus. it takes a toll on social life, but i guess that&#039;s the price we all have to go through when taking medications."
