Morning After app reveals how long it takes to sober up
The festive season is in full swing and over-indulgence is often par for the Christmas course.
However, a sobering new app reveals just how long it takes for your body to get back to the right side of the legal limit after a drinking session.
The Morning After Calculator lets you tot up how many hours it takes to get your favourite tipple out of your system, and those favouring the stronger stuff might be in for a shock.
The new app is aimed at letting drinkers know just how long it takes for their favourite tipple to leave their system...with even four drinks across an evening rendering people unsafe to drive the next morning
The high percentage shot Jagermeister - often served alongside other drinks - can quickly tot up. Four shots of the spirit can add an extra six hours of sobering up time
Five pints of lager, served up before midnight, will leave drinkers on the wrong side of the legal limit until 11:30 the next day. Right: Strong cider served in 500ml bottles such as Magners or Bulmers take around ten hours to leave the body
The campaign behind the app encourages people to drink more responsibly to avoid accidents on the roads after a night out and a drink drive conviction.
After consuming a bottle of prosecco - which carries a 12 per cent alcohol volume - drinkers wouldn't be safe to drive again for at least ten hours.
If the last drink is consumed at midnight, the drinker will still be unsafe to drive in the next morning's rush hour.
And mixing drinks is even more risky. Two glasses of prosecco, followed by four margaritas would leave you in the danger zone for at least 16 hours, well into the next day.
A five-pint lager session would leave revellers unsafe to get back behind the wheel until at least 12.5 hours later - the early afternoon of the next day if drinking stops at midnight.
A Christmas favourite, a bottle of prosecco - containing six glassses - takes ten hours to recover fully from. Right: Four mojitos - made with white rum - needs 9.5 hours to pass before it's safe to drive again
Alcopops may be out of fashion but they're a lighter option; four Smirnoff ice takes 5.5 hours to leave the system, according to the calculator
The Morning After campaign, which was first established in 2006, warns: 'It takes a lot longer than most people think for alcohol to pass through the body.
'On average it takes around one hour per unit of alcohol, though this can vary depending on a number of factors.
'Because of this, there is a real risk that people who would not dream of driving after drinking may still be unwittingly over the drink drive limit the morning after.
'This includes people going about everyday activities such as driving to work, doing the school run, popping to the shops or going to see friends.'
In September, television presenter Kirsty Gallacher pleaded guilty to drink driving after she was stopped at 11.30am as she was on her way to pick up her children.
The 41-year-old Sky Sports star was pulled over by police in August after she was spotted 'driving erratically'.
Miss Gallacher, who had enjoyed a night out with friends at the Winning Post pub in Winkfield, Berkshire, the previous evening, was on her way to collect sons Oscar, nine, and Jude, six, from her ex-husband's home when she was stopped in Eton.
The presenter was banned from driving for two years and ordered to carry out 100 hours of unpaid community work.
