Treat yourself to a well-deserved glass of wine each night, assuming it's harmless?

Unfortunately for you, it means you're breaching the 14 units a week recommended by health chiefs. 

That limit – considered the tipping point in terms of health-related harms – equates to about six pints of beer or a bottle-and-a-half of wine. 

MailOnline's handy calculator can tot up how many units you sink each week, as well as how that compares to the UK's guideline.

Simply answer how many beers, wines, alcopops and spirits you drink on a weekly basis.

The NHS advises anyone who does consume 14 units a week to spread this evenly over at least three days.

It also says that the safest approach is to not drink alcohol at all for women who are pregnant or trying for a baby.

'One unit equals 10ml or 8g of pure alcohol, which is around the amount of alcohol the average adult can process in an hour,' the NHS explains on its alcohol advice section.

'You can work out how many units there are in any drink by multiplying the total volume of a drink (in ml) by its ABV (measured as a percentage) and dividing the result by 1,000.'
