Why do some people talk nonsense when they drink?

I think that the wine is almost finished, and the reaction is slow at this time. Nonsense is a manifestation of drinking, a habit and an involuntary practice. He drinks to such an extent that he can't stand it if he doesn't talk, so he can't understand anything others say. Some people say things they shouldn't say, which is out of control. But the common phenomenon is that drinking and talking nonsense is not his intention, but a habitual action!
