I was diagnosed with ADHD when I was probably in 2nd grade and took Adderall, Ritalin and Concerta. I stopped taking them about 3 months prior to finishing my Bachelors of Computer Science. I have now been 8 months with out it and have been working at my new job quite well. Prior to that for the last 2 years of my education I would only take my medication when I needed to study hard or had a test.
