I would say the only two things that have helped me from AVRT was the idea that I never drink and I'm not changing my mind. It's been mantra for me. I'm pretty willful when I am firm about my decision.
Support was the second most critical thing for me. Once alcohol disappeared from my life, a HUGE whole of emotions I refeused to experience remained, as did all the problems I created by drinking. I needed support to make it through. Having a place like this talk to others who unstand what this is like has been so valuable. Be well.
