I know this is an old question -- but short answer is, no! While medication helps a lot of people, not all need it or should stay on it once they get on. I was on medication for three years -- just long enough to graduate high school and then get my professional life geared around to accommodate. After that, with some psych oversight, I tapered down and went off them. It's been 10 years, and still doing well -- VERY noticeably ADHD, but functioning just fine in my world.
