From your example towards the bottom of your shopping trip, that sounds to me like you are understimulated. You sound very intelligent and it almost sounds to me like your brain is just trying to find a way to occupy itself in an otherwise boring situation. I'm not dismissing the possibility of also having ADHD. Many people with ADHD are also gifted. This is just a thought I had.

As for Adderall - I have not ever taken it. I have taken a multitude of other stimulant medications, similar to Adderall, for the treatment of ADHD. I'm trying to think back to when I first took medication. So my ADHD makes it feel like I can't hold one thought in my head for an extended period of time. I used to describe thoughts as being like a TV in fast forward. I think about many things very quickly and jump from thought to thought. Before I was medicated, and when I am not medicated now, in order to focus mentally, I am usually moving physically (leg jiggling, tapping, pacing, bouncing in place, rolling pens, swiveling the desk chair, etc.) I remember when I first took medication, everything just sort of relaxed. I felt less tense. I could actually sit down and just think. I remember having a tutoring session that afternoon and my tutor commented on how focused I was that day (she didn't know of my diagnosis or that I was beginning treatment). It was also after I began medication that I began to be able to nap. I could never settle down long enough to take a nap before.

I want to say though, that studies have shown that even people without ADHD will see benefits of ADHD medication. Hence why stimulants are abused in school and in work environments. While ADHD medication will level the playing field for someone with ADHD, ADHD medication has also been known to enhance anyone's performance and productivity, regardless of diagnosis.

If you do seek a professional diagnosis, a thorough diagnostician will do a full workup of your school history, work history, ask you about your relationships, talk to your family members about their observations of you over the years, what you were like as a child, etc. Symptoms have to impair functioning in multiple areas of your life in order to be rendered a diagnosis.
