In my early days of sobriety, I could not deal with the idea of never drinking again. Forever.
It didn't work in my thick skull. It was overwhelming. It seemed impossible.
So, as I also learned in AA, just don't drink today. I can handle that.
Nine and a half years later I'm still sober. One day at a time. I still use it, you see. It's sort of my mantra.
I can't think of anything that I would do forever. Except drink. And now I can choose not to just for today.
Works for me, and I hope it works for you.
