Put some vinegar in a cheap vodka bottle. Tell her that if she wants the good stuff, she can go herself. My dad calls it the Kool-Aid syndrome after his brother, who had to make the koolaid once a week like all the other siblings, started making it really really bad until they stopped asking him.

On a more serious note, I'm really disturbed by the fascination with drinking in culture (well, in America anyway. I see you're a Rocky person, but could be Canada). I've found that it's as fun as the movies make it seem maybe 1/50 times, and every other time it just sucks for people. Sorry you have to go through that. Do you think it's too late to change her? It's hard to remember you love someone who is so deeply affected by alcoholism.
