I think that anyone that drinks to the point of drunkenness is going to act drastically different. Since it lowers inhibitions, people tend to let out those things that they keep inside more, they do things they wouldn't do if they were sober. I think in some ways that a person that seems calm and collected or seems like a "norm" would act even more outrageously because they keep things inside even more.

Idk that there is much of a rule about drunkenness that would be isolated to bpd, but then that's just my perspective.
