A man has told how a lifelong addiction to Diet Coke has come to dominate his life.
Darren Jones, 38, can't go a day without downing 18 cans of the soft drink - the equivalent of 42 litres a week, costing him around £3,000 a year.
Over the past decade his habit has gradually worsened and now he can't leave the house without a bottle of Coca Cola.
Astonishingly the father of two, from Stockport, Greater Manchester insists his huge intake - which amounts to 65,700 cans over the past ten years - hasn't caused him any medical or dental problems
But he did say that if he doesn't get his daily fix he can get moody and irritable.
He said: 'I don't really drink anything else. When I don't have it my family says I'm a nightmare to be around.'
Although he has bottles stored in his kitchen he doesn't let his children Abbie, seven, and James, six, drink the sugar-free soft drink.
Despite Mr Jones insisting that his addiction hasn't affected his health, health experts have warned otherwise.
Dr Vicci Owen-Smith, NHS Stockport's deputy director of public health, said: 'Diet Coke has artificial sweetener and contains caffeine. Too much of either of these may cause harm.'
In June, U.S. researchers confirmed artificial sweeteners and diet drinks cause weight gain, possibly by boosting a craving for sugary foods.
Diet Coke was first introduced in the U.S. on August 9, 1982, becoming the first new brand since 1886 to use the Coca-Cola trademark.
It was sweetened with aspartame, to save money, after the sweetener became available in the U.S. the following year.
A Coca-Cola spokesperson commented: 'Our packaging clearly shows caffeine, calorie and sugar content in relation to recommended daily guidelines.'
Mother-of-two Claire Ayton was also revealed to be a Diet Coke addict earlier this year. She said she felt constantly tired, thirsty and found it impossible to lose weight as a consequence.
