I have a comment on the ADD thing as well, as I am very close to a few people that have it. Not everyone benefits from every kind of medication for ADD. I don't know if you've done this yet but another option you have is to find a qualified ADD coach. This is not like therapy but rather to have someone to keep you motivated and find strategies to reach your goals while working around the attention issues. For a lot of people this is the single most helpful part of treatment. A good book that mentions how this should work is called Driven to Distraction, which might be a great read for you.
