That's how I usually am Azena. Occasionally two beers and I'll be tipsy but it all depends on mind set I've discovered. If I went out with some friends to shoot pool determined to get hammered out of my mind I'd be the one driving home cause everyone else would get nice and toasted and I would only have the slightest buzz usually. lol.
But if I went out wanting to just have some fun, shoot a couple games and relax, next thing I know I'm a beer and a half in and well on my way to the land of drunkering.
