I don't think so. The more you drink the more your body directs its efforts to drink more, so in turn all your available senses are directed into NOT spilling and actually moving the pint to your mouth
I study the actions of drunken men and women. I do studies by taking part in the drinking ritual myself and sometimes tape the night for amusement..<cough> study purposes.
My studies show your body directs all its efforts into drinking more, this directs energy from feeling pain, walking straight and upright and also talking sensibly and clearly.
No, and I've never seen that. In fact I don't understand what you mean. The only time I've been drunk and on the floor is when I'm not longer able to stand and my brain has ceased to work. In effect, I'm dead...
