I really must say that people who do mean or completely boneheaded things when drunk are people who would want to do those things anyway if there were no hard consequences for doing so. I attribute this to the fact that I am a pretty peaceful and benign person and the few times I`ve gotten REALLY hammered, I never did anything more regretable than clog up a toilet with poop and then make a big and vocal deal about unclogging it.
But that said, I very rarely get hammered because whenever I feel myself getting too drunk, I tend to stop drinking or at least slow down. I don`t really understand people who fail to have this mechanism or level of control and proceed to drink until they have to throwup. It`s always been a very avoidable eventuallity for me, but I guess not everyone is the same.
