An Irishman drinks 81 pints in one weekend and claims he didn't even have a hangover

A Guinness lover has claimed he drank 81 pints in one weekend and didn't even have a hangover.

Sean Bryan, 33, from Kilkenny, Ireland, shared the details of his big weekend on Facebook.

While some praised it, others said it was “dangerous.” labeled him an 'idiot' for 'risking his life'.

The man said he started drinking at the local pub at 1pm on December 29 and had his 81st pint at 9pm over the next two days on New Year's Eve – before going to bed before midnight.

Sean said he spent a whopping €400 (£344) on beer over the three days and says Guinness is his favorite alcoholic drink.

But after the 6ft tall Guinness enthusiast shared his feats online, many social media users were unimpressed by his stunt due to the health risks and said he was 'stupid' for bragging about it.

Hundreds of Facebook users branded his behavior 'dangerous', while others said they wouldn't drink that much booze in a month.

According to the NHS, men and women are not advised to regularly drink more than 14 units of alcohol per week.

This is equivalent to six pints of medium strength beer or ten small glasses of lower strength wine. Long-term alcohol abuse can result in a weakened immune system, high blood pressure, liver disease and increase the risk of stroke.

A pint of Guinness contains 210 calories and has an alcohol content of 2.3 per pint.

In Sean's case, he found himself guzzling more than 17,000 liquid calories in three days, resulting in 186.3 alcohol units – more than 13 times the recommended weekly alcohol limit.

Despite others raising safety concerns about the safety crew worker's drinking, the 33-year-old said he does not count calories and believes his drinking session was not dangerous because it was a one-off event.

“I don't think it's dangerous to do this every now and then, but if you did it week after week it would be,” he said.

'But because it was a one-off and because it was Christmas, [it was okay] and I never actually count calories.

'I started drinking on Friday December 29 and had my first Guinness in the local pub around 1pm.

'I went home every night, but [returned every day and] stayed in the pub drinking all weekend.

'I drank 81 pints of Guinness, breaking my last record of 78. It wasn't really a challenge I set myself, it just became a thrill between friends.

'[Over the 81 pint Guinness weekend]I was just drinking in the pub with friends.

'I drank my 81st pint on Sunday 31 December at 9pm and then went home [from the pub] at 10 p.m., so I didn't continue drinking into the new year. I wasn't hungover, but I was quite tired [after the weekend of drinking].

'An average pint of Guinness in a pub in Europe costs about five euros and in total I spent about four hundred euros on pints of Guinness [over the three days].'

Sean said that after completing his 81 pint stunt, his friends have now challenged him to drink 100 Guinnesses in three days, but luckily he has no intention of trying as he thinks this challenge may be impossible to complete.

Sean said: 'People in the comments said I would be dead before I was 40 and that I looked very unhealthy and I kind of took this to heart.

'[Drinking the 81 Guinnesses] It's over now, but I wouldn't want young people to read this and think of me as a role model or anything like that.

'I just did it for some crack. However, it was fun to do at the time and I think it's fine to do as a one-time activity.

'Everyone has an opinion on social media. That's the generation we're growing up in now and that's how it is.'

After revealing his antics on social media, his post was flooded with more than 3,900 comments – many of which criticized him for “bragging” about them or for being concerned about his health.

One user said: 'Impressive*not.' A second user said: 'It's a stupid thing to brag about no matter what you say.'

One user wrote: 'Stupidity at its best, bragging that they can drink themselves to death.

“I'd have more respect for the guy if he told everyone he's been sober for 81 days. Much more of an achievement.'

A fourth commented: 'A huge amount of stout, I wouldn't even drink that much in a month.'

Sean followed up his original post a few days later, announcing that after the amount of “abuse and health advice” he received in response to his claims, he was enjoying a shandy on his birthday instead.

Sean said: 'Given the abuse and health advice I received on New Year's Eve from the many wonderful people, doctors and psychiatrists in this group, I celebrated my birthday with a shandy but insisted on a Guinness glass.'

Alcohol Change UK said they could not comment on the specific incident but provided the following guidance.

'The UK Chief Medical Officers guidelines for low-risk drinking recommend staying below 14 units per week (that's about six pints of regular strength beer or one and a half bottles of wine), and spreading your intake over three days or more with a few alcoholic drinks. – also days off.

'Regularly drinking above the recommended low-risk guidelines can be harmful to our health.'
