fall in between

ROBERT SIEGEL, HOST:
If you have a glass of wine with dinner tonight, you're in good company. If that one drink turns into three or four, well, that's not unusual, but if this happens a few times a week, you fall into a category of drinking that may surprise you. NPR's Allison Aubrey reports on a new study from the Centers for Disease Control and Prevention.
ALLISON AUBREY, BYLINE: A lot of us make the assumption that there are just two kinds of drinkers - those of us who have a glass of wine or beer with dinner and those who are alcoholics and need help, but CDC researcher Robert Brewer says, this is not an accurate picture. Most people fall into a different category.
ROBERT BREWER: The reality of the situation is that most people - most drinkers - most adults who drink - there are people who are drinking maybe a couple of times during the week and then typically drinking a large amount often on weekends.
AUBREY: And this means they're drinking too much.
BREWER: About one in three adults drink excessively.
AUBREY: And what is excessive drinking? Well, it's a lot less than you might think. Say, I have a glass of wine with dinner most nights of the week. Then on Saturday night, I go out, and I have a cocktail, a beer or maybe some more wine. By Sunday, I've had eight drinks for the week, and this is considered excessive.
