Hi LookingToBeFree, I am glad you found us here. From where I sit, I'veHadEnough described a great start with this avrt stuff. That's a good understanding of the mindful awareness and separation aspect of this cognitive approach to soberness.
The next part, the part where the rubber meets the road, is to make your commitment to never drinking again, call it your Big Plan. This makes a two pronged attack on your AV. It is necessary for sobriety, and it also makes it easy to become aware of and to recognize that beast. A twofer. Remember that doubt in yourself is beast activity too. GT has helped with a notation about that idea in your post.
Set that confidence-in-yourself dial to 11, and do this thing. You can, you know, you most assuredly can do it. Now is a perfect time too. There is no try, because that is the beast working you. It is terrifying to imagine, maybe, but just remember that it is your beast that is scared sh!tless. Too bad for it. Onward.
