"I am a 19 year old studying Chemical Engineering in college, and I would say that Concerta has helped me so much. I started taking this in 18mg doses in 3rd grade and I was then able make straight A's through 5th grade. I then began taking a higher dosage of 36mg in middle school and continued taking it until this day.  I graduated within the top 4% of my high school class and I am doing very well in college.  The single greatest thing about Concerta at 36mg dosage, is that I can study and stay focused up to 12 hours straight! I have become an extremely hard worker and other students, who don't have ADD, simply can't keep up with me because of the amount of time I am able to put into my studies.  I would highly recommend Concerta."
