Hi Anyistoomuch. Thanks for posting this. I can so much relate to your story. I too had a favorite sushi bar where I would go to "decompress" and to "treat myself". I so much enjoyed those 2-3 glasses of wine... hated the fact I would then pick up a full bottle on my way back and then drink all of it before passing out.
I too have an extremely difficult mother. Spending any amount of time with her, even a brief conversation over the phone, lead me strait to the bottle. She was so toxic to me that I finally had to cut all ties. I have not talked to or seen her in over 3.5 years. Cutting ties was not easy and I am still healing from my wounds and the self-defeating feelings of guilt and resentment.
Congratulations to you on 50 days. I agree with the other posts regarding the technique of visualizing what most likely will happen if you decide to have that one "relaxing" drink. And, it is a decision. That is the good news here.
You are doing great! Just keep on keep'n on!!!
