A teenager was taken to hospital after overdosing on espresso coffee.
Jasmine Willis, 17, developed a fever and began hyperventilating after drinking seven double espressos while working at her family's sandwich shop.
The student, of Stanley, County Durham, was taken to the University Hospital of North Durham, where doctors confirmed she had overdosed on caffeine.
She has since made a full recovery and is now warning others about the dangers of excessive coffee drinking.
Ms Willis, who had thought the coffees were single measures, said the effects were so severe that she began laughing and crying for no reason while serving customers at the shop.
