French drink a lot but always moderatly. We rarely get drunk. But you have the glass of wine at every meal, the "apero", a sacred tradition and of course the parties. Also, most french drink regularly during the week. We don't drink more during the week end or not a lot more.
I was very surprised in Copenhagen to see how people behaved during the week days and went completely crazy during the week end. I've never seen so many people that drunk in Paris, at the same time.
One another thing I noticed about an American (US ) this time. Though I don't want to generalize. Once, at one of my teenage parties (I was 17 I think), a friend of mine had brought his american penpal who was visiting, who was our age.
Very cool guy when he was sober. But it was obvious that guy didn't have the same access to alcohol than we had. He drank all he could as fast as he could. There wasn't the "binge drinking" notion but that's exactly what it was. We all told him it was cool, that he could calm down, that there was plenty of alcohol and that we were gonna stay all night... but he basically didn't get it... he seemed to have an urge to drink. After a while, I told my friend to leave with him because I didn't want to call the emergencies because a guy passed out at my place...
