cacaringsister, I'm a couple hours north of you and I also work a secular recovery. Not just for my own addiction, but also for working with the issues with my addicted mother. Since my grandma raised me, its more like having an addicted sister and I feel right at home here at the Friends and Family forum. Everyone knows that I work a secular program (SMART) and they are okay with that.
For me, the important part is that I work some type of program. Whether NarAnon, AlAnon or SMART, i think its important.
I do know many who don't believe in a god get a lot out of AlAnon. The trick is to find the right group. Remember a HP (Higher Power) doesn't have to be god, it can be the Group Of family members affected by Drink (shortened to GOD) or even a book. In fact, I had a friend who had a book that seemed to give her peace and advice when she had problems. That was her HP.
Whether SMART or AlAnon, any program has many benefits when we feel we are battling with the issues you and I share.
