EVEN before we reached the concert site, there were people strewn all over the ground as their friends tried to get them into the recovery position.
At the gate, the Garda Public Order Unit were helping a girl to get medical attention as the first act of the night, Calvin Harris, was entertaining the crowds.
What followed a night of brilliant music, sadly overshadowed by the few who tried to turn the concert into drug-fuelled mayhem as stretcher after stretcher brought the wounded away.
Don't for a second think that the concert was full of 'youths' and troublemakers. There were people from all walks of life there.
I spoke to one man who assured me that at the age of 53 this was definitely his last concert. An American beside me was shocked at the availability of drugs and the bizarre need of many to go shirtless.
By the end of Snoop Dogg's set, my friends and I had succeeded in getting against the barrier and possibly even getting high through passive smoking.
Everything then moved up a gear when Tinie Tempah came on.
The atmosphere was electric but there was an inexplicable tone of aggression. Fights were breaking out behind us.
Mostly minor scuffles but at one point I got hit by a glass bottle. Thankfully it didn't smash but my shoulder was left bruised.
A couple were openly engaging in a sex act and people seemed to have no fear about popping pills.
Our vantage point just to the left of the stage meant that we were also positioned to see all the drama that unfolded as a steady flow of people were carried to the first aid tent.
Miami To Ibiza or (Miami To Dublin, as Tempah rephrased it) sparked the mosh-like attitude and we witnessed the first of two people we would see stretchered past us surrounded by medics
Swedish House Mafia arrived just as the sun set behind the stage.
The party then really kicked off for people, like me, who were there to see them for the last time.
But the rough element still existed and we witnessed the chaos of a continuous line of people being taken out in front of us, some being ejected and some carried to the first aid tent.
When a bouncer passed a glass of water to a man behind me, he just used it to swallow a pill that I can only presume was ecstasy.
He had earlier asked me if I had any E-tabs.
Despite this, for most of the crowd it was a superb night summed up by the encore of Save The World Tonight that had 45,000 people singing as one.
Pity about the few who set out to turn it into the concert from hell.
