I relapsed for decades. I finally quit, with the help of an addiction counselor, AA, and this forum. But I have to tell you, AA meetings helped the most when things got rough and my mind was playing it's tricks. I still go to meetings and I'm finally working the steps to find peace of mind.
The program works. It's that simple. I didn't believe in AA either but my counselor encouraged me to go. He said no one wants to go.. haha. You just have to decide how badly you want sobriety. If you want it you can have it. It is a miracle for those who have been unable to quit any other way.
