I don't think any habit just stops, especially one that one believes is caused by someone else. It's your habit, your problem, your decision to drink so you have to actually do something to stop it, it isn't its own behavior, out there, not a part of you.

My brother had a drinking situation similar to yours (but without the next wife -- he's been married 4 times) and hit bottom as an alcoholic and gave it up cold turkey, about 30-35 years ago (after the lacerations to his face healed from falling down a flight of cement steps with a glass in his hand (he still wears a beard to cover the scars on his chin), pulling himself up and onto his girlfriend's (he was still married to wife 3) white couch and bleeding all over it (he'd already maxed out her credit cards and been fired from his job for not showing up; his coworkers found him passed out/drunk at the hotel in the other city, where they were doing a presentation he did not show up for), kind of ending that relationship, she drank too but not quite like that. He lost his car, driving drunk between North Carolina and Washington, D.C., managed to sell it to one of the jailers, got on a bus and continued north. . . eventually he took a train on a drinking binge, coast-to-coast (D.C. to San Francisco) and called me (I lived in D.C.) from San Francisco to tell me he had $12.38 left, what should he do? Fortunately our father's sister lives in San Francisco and I gave him her number, called her faster to clue her in that he'd be calling and what was going on, and she and my father got him back to the East Coast and into treatment. The halfway house had to close, earlier than the end of his treatment but he borrowed money from me, got a great job, an apartment, and cold turkey'd it from then to now (late-1970's/very early 1980's). He found wife 4 and is living happily ever after. He will not even eat food that has liquor cooked/baked into it.

I would get some treatment, not drink at all, ever again, if I were you.
