Electric Picnic produced more FOMO than any other event this year, a new survey has shown.
Out of 350 respondents, 29% said they wished they had gone to the Stradbally festival.
Coldplay's Croke Park gig in July came in second place, turning 24% green with envy.
TV shows were also a big source of FOMO, with half of those surveyed regretting not tuning in to Game of Thrones.
Singletons were more likely to suffer FOMO than people in relationships, as just 25% said they felt jealous of their unattached friends.
On the other hand, 55% of singles would apparently prefer to have an other half.
The survey was carried out by NOW TV and targeted men and women between the ages of 18 and 45.
