It can be easy to lose sight of how much alcohol you drink, especially in the run-up to Christmas.
But a handy calculator can now tally up how much you consume, compared to the UK average.
The tool, based on a survey of more than 6,000 people, even works out how many hidden calories you consume when you indulge in your favourite tipple.
The calculator, developed by Public Health England in collaboration with Drinkaware, starts off by quizzing users on where they live.
Participants are also questioned on how old they are and whether they are male or female.
It then asks them how often they drink – every week, twice a month or less, once a month or less, or never.
The calculator then quizzes a user to highlight the days of the week they typically drink. If this varies, it prompts them to use the past seven days as a guide.
It then asks how often the user overindulges in alcohol in one sitting; defined as two-and-a-half pints or medium glasses of wine, six shots of spirits or four-and-a-half bottles of beer.
The calculator then presents how the user’s drinking compares to others of the same sex.
It also works out the number of units they get through in a week and how many calories this equates to.
The NHS recommends adults drink no more than 14 units of alcohol a week, which they should spread over at least three days.
This is around six pints of medium-strength beer or 10 small glasses of low-strength wine.
The NHS also advises people have several alcohol-free days a week.
However, some claim this can lead to drinkers overindulging on the days they do treat themselves.
The calculator comes after experts threatened to stop helping Public Health England if it continues to work with companies that produce and sell alcohol.
They claim PHE’s reputation will be at ‘significant risk’ if it goes ahead with the planned campaign with Drinkaware, which is urging middle-aged people to have set days when they abstain from alcohol.
Although Drinkaware claims to be independent, it openly receives funding from alcohol producers, pub companies and supermarkets.
Experts worry this may create a conflict of interest.
PHE’s chief alcohol adviser, Professor Sir Ian Gilmore, resigned last month because of the body’s collaboration with Drinkaware.
Another of the body’s alcohol advisers, Professor Petra Meier, has also signed the letter, along with Professors Mark Petticrew and Dame Sally Macintyre, who have advised on official drinking guidelines.
The editor of the prestigious medical journal The Lancet, Richard Horton, has also signed.
And the director of the UK centre for tobacco and alcohol studies, Professor John Britton, is threatening to resign his post as PHE’s chief smoking advisor.
Even the World Health Organization has criticised the pairing, with experts saying they are ‘alarmed’ PHE officials do not seem bothered by the collaboration.
But Drinkaware’s chief executive Duncan Selbie argues the organisation is a charity and not part of the alcohol industry.
