Welcome to the site, Kazza. I think the symptoms of ADD can also be symptoms of other things. You say you still "daydream" and I know I "withdrew" from my world into my daydreams heavily as a child (and had to enter therapy because of that pretty much) and that alone could cause poor concentration, memory, and attention problems! I wasn't "there" to do the concentrating or attending. My mother died when I was quite young and my stepmother was pretty harsh and I was a mess psychologically. Did you have any "problems" as a kid; what you thought was ADD might just have been psycho-social problems of growing up (nice way of putting "immature" like I was :-)

Have you ever been evaluated by a doctor or psychologist? They'd be the best people to ask about yourself personally. We're just peers here. But yes, I think we can outgrow stuff.
