Getting drunk

Es
Spring break is next week. I have a friend who has a one month old daughter and is breast feeding. She has not "had fun" since she was pregnant and she wants to get really drunk on spring break. Since she's breast feeding, what should she do? I've told her its a bad idea and that she shouldn't get drunk. If she wants to drink a few, then I guess that's okay. But she wants to get really drunk. What should I tell her she can do? She's only gonna do that for 2 nights. Can she pump it out or what? How does she get it all out of her system so she can breast again? How long should she wait? I don't know what else to tell her
