I just heard about an alternative to AA called Rational Recovery, and the founder of this system has stated it also works for other addictions, not just drinking. He has an online sequence of short pages that lead you through a process where the claim is that afterwards (only a few minutes) you will be addiction free. I went through it myself, and I think it's a good thing to do and might even bring about the breakthrough he says will happen. Here's a link directly to this sequence:
Note: This guy is very anti-AA for some reason. I suggest ignoring his tirade and just go through these flashcards. They're helpful on their own, and you don't have to buy into his philosophy about why AA is bad to benefit. It's just an alternate way of looking at things and gives you another way to deal with addictive behavior, and I believe it's a powerful tool. There might not be a one size fits all path to recovery, though AA is tried and true (in my opinion). I say find the one that works for you, and this one's good. It's called Rational Recovery, I believe, because it's based on scientific principles (neuroscience and psychology) and it rejects AA ideas like how addiction is incurable, you have to say you're an addict for the rest of your life, "one day at a time," going to meetings for the rest of your life, belief and surrender to a higher power, etc.
