This is something I guess I cannot understand about people who consume alcohol to the point of blacking out... For me the consequences are so harsh I just never seek to near that point. I achieve a certain level of buzz, and simply maintain it, sipping throughout the social event. It's quite pleasant, doesn't take many drinks to uphold, and I don't feel hungover in the morning. Maybe some of it is just "brain wiring"?
