Definitely. Just having a little can release your inhibitions, and really help with creativity.
I also find that having a couple of drinks, or a smoke, helps me speak more articulately, and to not mumble or stutter as much. So I always have a couple of martinis before I conduct a phone conference, or go to a meeting.
most of the time inhibitions are just an attempt to conform to "society's" norms
the obvious example would be gays/lesbians pretending to be straight when around homophobic people but the instinct to alter our behavior to fit into society also affecting our actions in almost every aspect of what we do
clothing
i don't merely mean the obvious thing of wearing something you're not comfortable in just because everyone else is wearing the same thing and you want to be part of the group
i mean the whole existance of clothing to begin with
if you have a kid grow up in a nudist colony, where the kid has no access to tv/internet and no exposure to any kind of clothing at all, then for that kid, the concept of clothes doesn't make sense
wearing clothes isn't natural without a person being exposed to clothing, that's why so many people get naked when when they get drunk, the intoxication is kind of "opening their eyes" sort of, so they question the purpouse for the existance of clothing and "realize" that clothing is pointless so they get naked, feel liberated from the constaints of clothes, but this state of mind doesn't carry over into soberness the next day because we have to wear clothes to fit into society's "norms" think of it this way, animals don't were clothes, animals would feel weird with clothes on
yes intoxication helps with creativity in much the same way, for a lot of people, there's tons of ideas floating around constantly in their minds, but when they get intoxicated, those "ideas" become not only music, as the tread started pointed out, but also "abstract" paintings and phantasmagorical novels, i used to hang out with a guy that made his living as a painter, he drank and did acid and he kept telling me "i just can't paint when i'm sober"
