The London Ambulance Service attended a record number of incidents on New Year's Day as revellers dialled 999 after bringing in 2014 with copious amounts of alcohol.
Paramedics attended 3,744 incidents on Wednesday - with the majority of those coming between midnight and 5am.
With an average of more than 500 calls per hour during that period, the service was almost five times busier than usual.
Extra treatment centres were also set up around central London, treating 438 patients and taking 88 to hospital.
Katy Millar, who is the LAS's Assistant Director of Operations, said: "It’s the busiest night of the year for us and unfortunately not everyone was using us wisely.
"Many of our medics were tied up helping people with drink related illnesses and injuries – preventing them from responding to other patients," she added.
Of the 2,588 emergency calls between midnight and 5am, the highest concentration was between 2am and 3am, when crews attended 612 incidents.
Hourly calls:
00.00 – 01.00 - 469
01.00 – 02.00 - 604
02.00 – 03.00 - 612
