We're a nation that's known for loving the odd drink or ten, but just what sort of damage are our poisons of choice doing to us? In this documentary, Doctor Javid Abdelmoneim explores the science behind drinking alcohol, including why the weekly recommended intake was lowered in January, with the men's limit cut by a third to 14 units per week. He also asks whether a nightcap can aid sleep, why some people get drunk quicker than others, what is behind the relatively healthy reputation of red wine and whether lining your stomach before drinking really lessens the effects of a night out.
