<human>: Ever since high school and all through university I've suspected I had ADHD. I find that even when I'm focused on a task that I enjoy and find interesting my mind still wanders and I get uncontrollable impulses. After some research, some online quiz's and even a visit to the GP it appears that I most likely have ADHD. I was still convinced that it wasn't a real disorder and that people who take Ritalin just lack good study/work habits and discipline.  

The other day I took half a 10mg Ritalin pill before studying and the difference was night and day. I actually felt calmer and the whole time and was able to stay focused on the same task for several hours.  The Ritalin didn't make my studying any more interesting, it just made me way less irritable and distracted by things going on around me (which is usually my problem).

Since my experience I've began to seriously consider that maybe I could benefit from a prescription but I'm still afraid that maybe I'm just another student with bad habits.  I'm looking to hear stories of people who found Ritalin to actually make a significant change in their ability to focus and their success as a student/employee.

Can you condense the text into three sentences or less?
