It's not a question of which way is 'right' or 'wrong'. It's a pragmatic matter of what works for the individual.
If you can stay abstinent by challenging any conflicting thoughts and beliefs about drinking you may have then obviously that's fine for you.
If you can't resolve your conflicting thoughts through a process of disputation then you may find it useful to introduce the idea of a 'Beast' and to dissociate from it's thinking and of course that's equally fine.
There is no one way that will work best for everyone.
