Amy Winehouse's grieving father told mourners at Tuesday's funeral service that his daughter had kicked her drug addiction three years prior to her death.

"Three years ago, Amy conquered her drug dependency," Mitch Winehouse said in the eulogy, which was excerpted in the Daily Mail. "The doctors said it was impossible but she really did it.  She was trying hard to deal with her drinking and had just completed 3 weeks of abstinence.

"She said, 'Dad I've had enough, I can't stand the look on your and the family's faces anymore.'"

Tuesday's funeral service took place at Edgwarebury Cemetery in North London. A family spokesperson had earlier announced that the funeral would be "a family and close friends affair."  Producer Mark Ronson and close friend Kelly Osbourne - who wore her hair in a beehive as a tribute to Amy's signature look - were among mourners present.

Metro had earlier reported Amy's ex-husband Blake Fielder-Civil was not granted compassionate leave to attend his ex-wife's funeral. Blake is serving a 32-month prison sentence for burglary and firearm possession. (His current girlfriend is now quoted in Metro and the Toronto Sun as telling The Sun that he never requested compassionate leave; saying he had "too much respect" to show up in handcuffs.

The Metro report suggested that Amy's ex would not have been welcome at the funeral even if the prison had let him out for the day.  Amy's father is believed to want Fielder-Civil far away from his daughter, even in death.

"Mitch thinks it would be a complete insult for him to be there and if he really loved Amy, he wouldn't cause any more heartache by showing up," Metro reports a source telling The Sun. "'He will always believe Blake is responsible for getting his daughter hooked on Class A drugs which marked the beginning of her self-destruction."

While there may be no love lost between Mitch and Blake, Amy's dad had kind words for his daughter's most recent boyfriend.

"Recently Amy found love with Reg [Traviss]. He helped her with her problems and Amy was looking forward to their future together. She was the happiest she has been for years."

Winehouse, 27, was found dead in her north London apartment on Saturday afternoon.

Unidentified friends of the singer said that she had engaged in "wild drinking" in North London in the days preceding her death.

In what is acknowledged to be her last public appearance, Winehouse joined her protégé and goddaughter Dionne Bromfield onstage at the iTunes Festival on Wednesday evening, the Mirror reported. Winehouse didn't perform herself, but danced and clapped along to Bromfield's performance. At Bromfield's prompting, she pitched in to the chorus of 'Mama Said', but her voice was barely audible.

"There was always a danger of something like this," one friend told The Mirror. "Her drinking is totally out of control. She's constantly out of ­control on vodka. She'd drink bottle after bottle and ­mixing those ­quantities with drugs is lethal."

But Kelly Osbourne - who spent an hour on the phone with Winehouse the day before she died - did not think her friend was in any immediate danger.

"I was speaking to her last night, she seemed ­absolutely fine, I don't understand how this could have ­happened," Osbourne told the Mirror.

Winehouse had spoken to her security guard, Andrew Morris, on Saturday morning at about 10 am, and told him she wanted to go to sleep. That is believed to be her last conversation.

When Morris went to wake her several hours later he found her dead.

Police sources told the UK newspaper that there were no signs of drugs at the house.

An autopsy was conducted on Monday, but the cause of death will not be determined until the toxicology tests are completed, which could take up to four weeks.

Some witnesses reported having seen Winehouse buying a variety of drugs in Camden around 10:30 pm on Friday night.  A source told The People that the singer bought cocaine, ecstasy, ketamine and possibly heroin.

"Amy seemed determined to have a big one on Friday night," the source said. "She was out in Camden on Friday evening, but seemed determined to carry on the party back at her flat.

"None of us know who was with her into the early hours of Saturday. But getting out of it was clearly her main priority of the night."

Amy's family told The Sun these reports were "nonsense."

Amy had seen a doctor on Friday evening, and she received a clean bill of health.

She had been getting regular checkups due to chronic weakened health.

"The doctor was happy with her condition," a source told The Sun. "When he left on Friday night he had no concerns. Less than 24 hours later she was found dead."

Amy saw her mother, Janis Winehouse, the day before she died, and Janis was concerned for her well-being.

"She seemed out of it. But her passing so suddenly still hasn't hit me." Still, Janis Winehouse felt that it was "only a matter of time" before tragedy took her young daughter.

Winehouse's father, a jazz musician and part-time taxi driver, was preparing for a show at a jazz club in New York City when he heard of his daughter's death. 

In what may have been Amy's last public comment, she wrote "I'm very proud of my dad," in an email to the New York Post on Friday

A few days before her death, Mitch Winehouse also spoke to the New York Post about his daughter.

"Frankly she's had her ups and downs," he said.

According to Tuesday's tribute, Mitch felt that his daughter was "up" at the end.

He spoke of her last hours at home playing the drums, and talked about her security guard finding her unresponsive later that day.

"But knowing she wasn't depressed, knowing she passed away, knowing she passed away happy, it makes us all feel better."
