the most helpful thing for me was realizing what that voice is. That it isn't the rational me that has my best interests at heart, it is the alcoholic me that wants only one thing. When I first started getting sober I wore a rubber band around my wrist. Whenever that voice would start talking I would snap the rubber band. It was a reminder to refocus and think about something else, take a walk, turn on some loud music, whatever I needed to do until the voice shut up.
