I finally got tired of being sick and tired. And I surrendered. It won. And I admitted it.
With AA in the beginning, SR everyday even now over 1 year later, I stayed sober.
But mostly, and others will say this too - I want to be sober MORE than I want to be drunk. Once that cosmic shift happens in your thinking, you will protect it at all costs.
Best of luck - sure wish I had the wisdom to see this coming when I was your age. Good for you for even asking the questions and taking action. It's not an easy road but one worth traveling.
