Hmmmm.... Well, if you wondered enough to be tested before, you might want to google about the difficulty of diagnosing ADD (especially without the hyperactive component) in gifted women.
Mine wasn't diagnosed until I had to get my dissertation done, other coping mechanisms had sufficed until a certain level of challenge. But, once I was diagnosed, it made a huge difference, I mean HUGE, and explained a lot about my life. So, I'm just sayin, might be worth another look...
Consider this quote, for instance: "Because people with ADD (ADHD) tend to be "reactive" to their environment, women with ADD (ADHD) may face a particularly difficult challenge when they try to stop focusing on the expectations of others and focus more on their own needs and desires." from one of the pages here: http://www.addvance.com/help/women/index.html
BTW, things like doodling, writing grocery lists, planning vactions, etc... while in meetings count as "can't keep still" even if you aren't shaking your leg, lol.
