Nothing works except an ultimatum. Better yet walk now and tell her that when she has been sober for a year to call you. That is if you love her. If you don't, you will stay and be an enabler.
If you stick around and have kids you will be stuck with a drunk who can't even be a half-decent mother. Later, your kids will hate you because she will make their lives hell. They will ask you why you didn't divorce her and you will feel like crap because you will not be able to answer this question without that "becaused I loved her" bs.
Begging, pleading, logic, facts are all useless. You might just as well talk to a wall.
