Whatever works for someone is always okay in my book! I go to Women for Sobriety meetings, SMART meetings and I also do go to AA meetings.
I get something out of every program. For me I had to learn to be more opened minded and willing to at least listen to other ideas and not to be so judgemental. I might not necessarily believe in God, but I don't have a problem listening to others talk about how it worked for them.
It's all about respecting people and their ideas even if they are the aren't the same as your own. At the end we are really all in this battle together!
