Have you committed to never drinking again? If you are never going to drink again and never going to change your mind what do you have to worry about?
I will never drink again and I will never change my mind. With that, drinking is not an issue for me now or ever. I don't drink. The same goes for tobacco as well.
I do hear my addictive voice from time to time but IT doesn't matter. It can't drink without my help and I don't drink. It can't dip snuff without my help and I don't dip snuff.
I am a Buddhist and from a Buddhist perspective. There are many thoughts and feelings that occur in my head. Just because I experience a thought or feeling doesn't make it true. Feelings are not facts, thoughts are not reality. I have choices. I can choose to pay attention to a particular thought or feeling and then act on it or I can choose to simply observe it and let it float on like a cloud in the sky. When the monkey mind is chattering on about the next shiny thing it sees and of course wants doesn't mean I have to react. I simply take refuge in my practice and watch the clouds of thoughts and feelings float by against the backdrop of a calm blue sky.
