Secular Connections - SoberRecovery : Alcoholism Drug Addiction Help and Information
Lots of useful advice and support here.
AA isn't the only way at all. I am a member and it has saved my life, but I have also used AVRT to successfully deal with my smoking addiction. I am a regular poster in both the 12 step and secular forums. I would just like to point out that not being a believer in God did not hinder my progress when I started.
Best wishes to you. See you around.
