"I got the feeling she's not one who can hold her liquor. She told us that her husband is always getting on her case about "drinking too much and talking too much." Umm... that would be a slight understatement."
Ding Ding Ding. I think we have a winner here. As in, it's very likely she woke up with a hangover wondering what happened last night. Let's face it, there's holding one's liquor and just, well, being a drunk. Good luck having any effect on her, avoidance at all costs the only way to deal with it. Good luck.
