Newly-crowned world champion Stuart Hall has turned his back on partying to concentrate on boxing.
The 33-year-old beat South African Vusi Malinga on points in Leeds on Saturday to become the new IBF bantamweight champion.
Hall needed 13 stitches to his face following the fight and he admits he is yet to toast his triumph with alcohol.
The Darlington-born fighter only started his professional career at the age of 28 after spending much of his youth enjoying the high life in Ibiza.
Hall said: "I went home after the fight and had four pints of orange juice. I will have some food and a few drinks on Christmas Day but my body needs looking after now because I want to prolong my career.
"After my earlier fights I would go away on long holidays but I can't do that now.
"I've got to the top and this is where the hard work starts. It's been amazing since Saturday night and I'm still in cuckoo land. It's just starting to sink in."
His unanimous victory over Malinga made him the oldest British fighter to win a world title at his first attempt.
He went on: "I've done so many mad things in my life and I've experienced so much - lows and highs, fat and skinny - but I wouldn't give up any of it.
"If I'd stuck at it properly maybe I would have got to the Olympics but I could have been on the drink now.
"You can't just be an athlete all your life. I got it out of the way - I've done them and enjoyed them.
"I've started concentrating on boxing and I'm world champion - and you can't get any higher than that."
