I'm not sure if the issue is that when some people refer to their "info addiction," it actually isn't an addiction (eg. "OMG! I am SOOO ADD sometimes!" says some person without ADD who needs a loving dose of perspective or strangulation) or if there are other things specific to me that mix with the info addiction such that having a positive goal I'm focusing on isn't enough.
Sorry for the previous curt response. This is essentially the only thing I'm trying to deal with right now because it leads to failure in all the things. And progress is slow because getting people to invest time in someone who has no money is seemingly impossible.
I did read your "I have ADHD" in the casual way that most people say it. I certainly don't have ADHD (not that I'm aware of, anyway). The only thing I can think to suggest is to seek professional help, if you haven't already.
