Yep, that's right. Apparently we experience a huge 315 days enduring a sore head thanks to one too many glasses of wine.
The survey of 2,000 Brits over the age of 18 also found that the average person will experience a painfully long seven-hour hangover at least once a month!
And when it comes to genders, women's last a massive nine hours, while men's are a slightly shorter, seven – a good thing to remember when your other half perks up before you.
Meanwhile, those living in the north have more hangovers than boozers in the south – with one in five Northerners experiencing more than four thick heads a month, compared to one in seven Southerners.
While no one enjoys a hangover, many revealed the worst part was missing out on doing other things. A quarter said they'd have more sex if they weren't hanging, while other said they'd be exercising or even learning a language.
The study - which was carried out for Macmillan Cancer as part of their Go Sober for October challenge – also discovered that sufferers could miss out on important parts of life, as ten per cent admitted they'd skipped a job interview due to a heavy night.
What's more, one in 13 had missed a first date and a shocking six per cent even confessed to not attending a funeral.
Hannah Redmond, from Macmillan Cancer Support, said: "This research shows hangovers are a waste of time and are causing people to miss out on everything from romance to their dream job."
