Does this sound like anyone you know? Darryl is 35, has a steady job, a stable home and good marriage, enjoys a few beers in front of the TV most nights - doesn't have what most people would call a drink problem.
In the United States alone there are probably around 36 million Darryls, according to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), which created the character, played by an actor on its website to help train doctors.
He doesn't exercise as much as maybe he should so he's a little overweight. At an average of four drinks a day, he is no alcoholic: but some experts now see him as a high-risk drinker and say he could succumb to "alcohol use disorder."
Millions more people across the developed world - who drink a few glasses of wine every night after work or look forward to three nights of repeated shots with chasers on the weekends - may today be adding up to a major health and social problem.
Could there be a pill to help them? . . . . .
