Although I am avid supporter of AA I also support the rights of anyone to do what they need to in order to stay sober. As long as you're sober and honestly happy about it then who cares and whose business is it what you do?
AA works for me because it helps me in many different ways. I am mindful daily of how recovery is not a destiny, it's an adventure. Also, it's given me the capability to build a social network of people who have my exact same goal in mind. I'm not saying I couldn't find that elsewhere but this is what works for me.
If you've found something and it works for you then I think that's fantastic.
