Carroll was wearing an electronic tag when he bought a lucky dip ticket in November 2002.
He went on a spending spree on cocaine, gambling and hookers that nearly killed him.
But while he says he has “absolutely no regrets” about living like a rock star for a decade, he believes David and Carol Martin – who shared the £66m jackpot with another winning ticket last weekend – should get out of their home town in the Scottish borders, as quickly a possible.
Carroll, 32, said: “This couple have said their daughter lives in Australia. My advice would be for them to emigrate there and start a new life.
“They won’t be able to live a normal life in Hawick.
“Family and friends will come out of the woodwork wanting their money and they will find themselves surrounded by lots of fake people.
“I gave £4m to family and friends – but some people wanted more and weren’t happy. Others who didn’t get anything stopped talking to me. I received hundreds of thousands of begging letters from strangers too.”
He also believes the Martins, both 54, and their 26-year-old daughter Lisa could be in danger after going public over their win.
“The kind of money this couple have won is kidnapping money,” he said. “I only had £9million. They have got three times as much as me.
“And there really are some people who will see it as a way of making money.
“Things went wrong straight away. I got my first death threat the day after I won and I’ve had thousands ever since. One said they’d chop my daughter up and send her back to me piece by piece.
“One was sending pictures of my whole family and details of where they lived. I was really worried. I began sleeping with a shotgun and I kept a blade in every room of my house.
“I didn’t get any help from the police. They didn’t want to know. I know I was a d***head in some respects, but when members of your family are being threatened like that you realise money isn’t everything.
“I told the police if anything happened it would be on their heads. Thankfully, nothing did.”
Carroll’s wild lifestyle saw him handed an ASBO for terrorising neighbours and he was twice jailed for drugs offences and affray.
The self-styled King of the Chavs was also hospitalised over binges which saw him spend £12,000 a week on drugs. Carroll also spent wildly on prostitutes. He once claimed: “I’ve slept with over 4,000 women. I once slept with more than 20 in one day with a mate in Amsterdam.”
As his winnings drained away to nothing, he was forced to live on benefits, then worked in biscuit factory in Scotland in 2011 before moving on to his current job in a slaughterhouse.
But despite everything, he admits he still buys lottery tickets in the hope of winning again. He said: “I’ve experienced more in a decade than most people would in two lifetimes.
“I’m much happier now. I still buy lottery tickets and would love to win.
“But the money takes over, and your life can become materialistic and meaningless.”
Carroll, originally from Downham Market in Norfolk, moved to Scotland to be closer to his 13-year-old daughter when his money ran out and spent eight months on benefits before getting work. He believes the move away from England has paid off handsomely.
He said: “I haven’t been in trouble since I left. I have put all my bad ways behind me. I was drinking two bottles of vodka a day when I had the money. But I haven’t touched the stuff for more than a year. I’m teetotal.”
While he earns just £400 a week working at the slaughterhouse and rents a modest flat which is a far cry from the English mansion he lived in, he insists he has no regrets.
He said: “You can’t regret anything. If you do then you get depressed, and I’m too happy to be depressed.”
The one thing he wishes he’d done while he had the money was pass his driving test.
He said: “I never did get my licence. I guess it was because I could just get a mate to sit beside me while I drove around in £50k cars with L-plates on.
“When the police pulled us over there was nothing they could do, because I had someone in the car with me.
“But I should have gone out and got my full licence. I’m still on my provisional now.”
Like all his favourite cars, including a Bentley, Rolls-Royce and souped-up Sierra Cosworth, there are no hangers-on in his life any more – and Carroll says he is happily single.
He said: “I spent £1 on a ticket and lived like a rock star for a decade. I had fun and don’t have any regrets.
“I was just as deserving as the next person – and it was my money to do what I liked with. I was 19 – who wouldn’t go off the rails at that age?”
Now older and hopefully wiser, Carroll’s life is a million miles from the hedonistic one of his millionaire days.
He said: “I haven’t touched drugs for four years.
“I go the local gym every day. I’m just a normal bloke.”
