I don't mean to be rude, but assuming you're not a doctor (and, even if you are, he's not your patient), I don't think it's good form to give medical advice on the Internet, particularly if it's advice that's dismissive of a mainstream treatment.

My two cents, don't rule anything out. I had a SO with adult ADD and medication made a world of difference. That's just one person, though, and everybody's different. Do talk to a doctor if you feel like you might have adult ADD. It's a very real thing, and there are lots of treatment options, both pharmacologic and not.

Thanks, I'll check them out!
