Your First AA Meeting<
It's normal to be nervous. I sure was.
As far as I know, Tom Cruise isn't a member AA. He's a member of something else ....
I promise you AA folks are not pod people. Set aside all that you think you know and just go with an open mind.
AA saved my life. I tried and tried and tried to quit on my own. I could not do it. I did not want to have to subscribe to others beliefs or conform to others ideas. I thought I would have to but I was way off.
Let us know how it goes!!
