Thanks everybody for the great pointers. I'll get reading right away. BTW I have attempted to get her on video but she runs away. And no she doesn't pass out every night, but a couple of nights a week. Definitely drunk every night though, and since we have a hard agreement that she won't drink if she is the only adult there then she waits until I come home before she starts. Even if I come home at 2 AM she waits and then immediately starts upon my arrival. Such dedication should be able to be channeled for good, no?
It's interesting to me that my dad was an alkie and none of us three kids are. He ended up running off with someone anyway so in some ways the damage was minimized.
