Do people do things they don't really mean under the influence of alcohol or do they do things they really want but are ashamed of wanting?

I always felt that alcohol was no excuse for my behavior. I felt like I was doing what I wanted to do, but was too inhibited to do while sober. I hear a lot of people saying they wouldn’t do whatever they did while drunk had they been sober. I believe that. I think we are often ashamed of what we do because our social inhibitions would prevent us from doing it if sober.

But I think people do what they really want to do while drunk; it’s just the social rules that prevent them, normally. So they are ashamed of their behavior, officially, but they can blame it on the drink and people will understand. Underneath, they are really happy about what they did, although often they may not admit that, even to themselves.

What say you?
