Send her a text one and a half to three hours after you meet her. Or if it is way late when you meet her and you are going to bed a half an hour can work as well. Just something like "Always good to meet someone with a sense of humor

" don't forget to sign it. This will help the interaction move forward rathe rthan her getting a text 16 hours later and her going "wait who was that". Then just a wait a day or so, or if she responds wait about as long as it took her to respond and invite her to hang out. That simple. You approach just like you would a girl who is sober. Chances of flake are a bit higher because she was way drunk at the time, but thats fine because there are plenty of fish. Personaly, a girl that extremely drunk is a turn off. I like my women with a bit of self controll. Also, when she is way drunk it is hard to get a solid read on who she really is.
