Ohhh how I can relate to what you are writing! I am more affraid of upcoming events than I am for the actual relapse it might cause. I have a monkey on my shoulder that whispers "this is a perfect occation to plan your relapse". Very exhausting! I hope the same strategy I used when I stopped smoking will work. I told myself that I am a non smoker. It worked from day one, and I had absolutely no relapses- 18 years now. And I was a heavy smoker (30 cigs a day!)
I will try the same with my drinking addiction. Don't know if it will work, but I can choose to make it work I guess
BUT I share the same fear as you, and every new sober individual on the planet!
Keep strong! I'll try to be too
(or as Fritz Perls said. You never try! You either do, or don't.)
