Yup I see it in my son too, who also takes meds. I think it's especially difficult with ADD, where the hyperactivity part is absent. You don't see the details around you and I think processing time is slower. And if you are pretty intelligent it looks to others (and eventually to you) that you are just very spacey, lazy or both. I wish I had been diagnosed as a kid because I really think my life would have been very different.
