Yep! I get those thoughts out of nowhere. I have to argue with myself, tell myself firmly that drinking is NOT an option anymore, that there's no more fun in it, only sickness and misery and risk. Sickness and misery I want to avoid and risk I don't want to take.
You have to re-train your brain/mind. Some do it with AA and the steps, some do it other ways, like the power of positive thinking, or, in my case, the power of negative thinking - I think of all the negatives that go with drinking and they greatly outweigh any positives.
Hang in there! Don't let your addict voice put you in a bad place. It is, after all, just a voice and can be shouted down or drowned out or just ignored.
