About ten years ago it got bad enough to seek medical attention. Once it was diagnosed (I was lucky, it took only several months instead of several years) I realized that I'd been having related symptoms for a lot longer and had been shrugging them off. So I'm not sure how long it's been affecting me, but the answer you're probably looking for is "about ten years".
I understand what ya mean... I'm only a freshan in college now, so when this hit me, I was 10 years old... around the 4th grade. Never knew there was such a thing before, so I didn't really know about it. Heh.
