Have you tried to stop trying to stop.... and instead started trying to start?
Instead of 'trying to quit'.
Choose to start being sober.
AA might not have stuck because you might not have yet chosen to be sober.
AA never stuck for me either when I was 'trying to quit'.
But when I chose to Be Sober.... AA became one of my strongest tools.
You can do it. Start 2017 early. Right now. Choose A Sober Life.
