Welcome to the family.
I hate to say what you already know, but she's not ready to get sober. Refusing help like meds is a clear statement of intent.
You would be totally within reason to set boundaries with her. Just be prepared to stick to the consequences.
We have a 'friends and family of alcoholics' forum further down the index page. Give it a read. They understand your situation and might have some words of wisdom to help you.
Have you ever been to AlAnon? Might be a good place to get support for yourself.
