She's probably bored, maybe I can help her find something productive to do. I'll do anything -- but what can I do to keep her off the sauce in the meantime?
Hi, if she has a tendency towards addiction these are not ideal circumstances, as she's home all day, and there are no consequences to her drinking.
She doesn't work, she doesn't drive; I'm not saying this caused her addiction but it's not helping either. On the other hand, it's not up to you to 'help her find something productive to do'. You're not her father.
Once she gets to the white knuckle, can't do without it stage, I would say she's on the way to alcoholism. Secret or daytime drinking is also a huge red flag.
She will have to make up her own mind to quit, but what incentive does she have at the moment?
Please think hard before going ahead with children.
