Hi soinlove,
I'm really sorry to read this.
I wish I had some insight that would help but it's a terrible fact that some of us will drink ourselves into the grave.
I'm not sure what you or any of us can do about that but be ready for the worst should it happen.
Some, like me, do manage a moment of clarity though and manage to claw ourselves back from the brink.
I'll be praying your loved one has that kind of epiphany.
