I also think it takes more than fear to remain on the journey of sobriety. My personal experience: I nearly burned down my landlord's house in January last year and the only reason I didn't die along with causing a block inferno was that he, by chance, had to come home in the middle of his fireman shift to pick some stuff (grateful he was a fireman). He found me blacked out (after 4 bottles of red wine) on the couch, the cooker was on fire, the kitchen and living room full of smoke, the fire alarm was faulty for some reason.
Anyway after 6 months sober I started drinking again and just told myself, I have taken the necessary preacautions to protect myself and others....the alcoholic/drug mind is crazy.
I think sobriety is a complete mind and lifestyle change....one day at a time...
