Alcohol just lowers your walls and if there were times when you usually bite your tongue, you'll just say. This sounds bad, but it has always been fun, to me, to lose control and just not worry about keeping your walls up and biting your tongue.

And some people don't like that 'out of control' feeling, and that's totally fine.
On occasion, when I'm feeling stressed, or bored, or happy, or celebratory, I have the urge to get drunk, because it means not having to worry or feel the need to control your image/surroundings. At least that's been my experience, anyway. :)
