I accepted and sought help on finding ways to be more flexible in my thinking, where as I could otherwise quickly and more easily give into drinking compulsions. I went about with a doctor ways to stop with short term medical help, and so lessen my fear (and put it into perspective) about would happen when I stop. I allowed myself to feel sobriety with even a short term (one day even) commitment to see how it stacked up vs. drinking. I instead looked at that my feeling anxious and maybe uncomfortable when stopping is the body slowly getting itself back to normal and part of the healing process.
Above all I started managing anxiety, better. It's a hell of a thing, but I forced myself to look back on times when I was managing it really well, and that was definetly without alcohol and binging.
