A light buzz is merely a small bonus when I drink; I primarily do so for the flavour of whatever's to be had at the moment. I like red wine with dinner, and throughout the week I'm generally having one of: a dram of scotch, or 2-3 beer.
The spectrum of different drinkers is far too wide to be able to pass judgement or qualify what's "over the line". As others have mentioned, if someone has three beer in a night and suddenly becomes a loser toward their family/friends, three's obviously too much. I always have different varieties of scotch/beer at home at any given time, because I love to try out and discover the many different varieties. However, I very rarely get anywhere close to "drunk", as I'm not too keen on the after-effects the following day, nor do I like losing total control over my faculties, ya know?
And with that...
