I would pay attention to it but I agree with another poster that a lot of what is said while intoxicated isn't completely sincere and often downright lunacy.
That said it seems to me that your AGF is demonstrating a realization of the hopelessness (in her mind) of her addiction. The can't live with it/can't live without it syndrome. My husband said that at least the last 7 or 8 years of his raging alcoholism was spent trying to find the good times when it was fun and they just weren't to be found anymore. Another poster on here, Pohsfriend, calls it circling the drain and I think that's a very accurate description.
Just keep posting and reading and educating yourself. Have you tried Al Anon yet?
