I needed both approaches too, like Tatsy.
Essentially, I made the Big Plan promise to myself to never drink again and never change my mind. Reading up on AVRT helped me to identify my Addictive Voice (AV) which it precisely defines as any thought, feeling, sensation, urge etc. that supports, suggests or promotes the possibility of future drinking. Mindfulness helps me separate from it.
As Tatsy said, we have to explore and learn a way that works for us. This forum helps me a lot and I'd encourage you to make use of it as part of your exploration and recovery.
