One thing in your original post that stands out is about someone offering you a drink. Where are you and what kind of situation are you in that a drink gets offered to you?
I'm really glad to see you back on the horse and committing yourself to stop drinking. I like the idea of journaling. I wrote down things all the time when I stopped. It helped to go back to reading some of those things.
If you can avoid situations where a drink is offered to you, then I would. But if for some reason you can't avoid it then do this. Drink that drink in your mind and then drink 12 more and then follow it all the way till the next morning and the guilt and shame you would feel. Just think it through and then say, "I feel great right now, I want to feel great in the morning too so I really don't want that drink!".
