Amy Winehouse had reportedly took a combination of drugs and alcohol over three days of partying on the run-up to her hospitalisation on Wednesday morning.

A source told the Sun that the bender started on Monday afternoon as soon as Amy arrived back from her recent run of gigs in the US: “It was like she had pressed the self-destruct button. She had been downing coke, pills and ketamine, vodka and Jack Daniel’s. Even Amy says she will be dead within one year.”

The singer started drinking with husband Blake Fielder-Civil at the Robert Inn near Heathrow airport, drinking vodka & lemonades. According to an onlooker, the pair “made repeated visits to the toilets during the two hours they were here. She went into both the ladies’ and men’s loos.”

After that, they were spotted in their favourite local, The Hawley Arms in Camden. An eyewitness reports similar behaviour: “She spent the evening knocking back Jack Daniel’s. They were acting quite strangely. Amy was backwards and forwards to the toilets all night.”

On Tuesday, she was observed being “very jittery” and “really out of it” at a cafe near the couple’s home in north London, then later in the day, she is believed to have started convulsing.

A friend of the couple’s told the newspaper: “Amy had boasted she hadn’t slept in three days and her intake was taking it’s toll. She looked like a zombie - white as a sheet and trembling. And I’ll never forget her eyes. They were dead, like a shark.”

“At one point she strummed her pink guitar and sang and I thought, ‘Yes, the girl is back’. But then she started rocking like a six-year-old and was wailing and sobbing.”

“[Then] Blake telephoned friends at 10pm, yelling ‘F***, f***, she’s having a fit!’”

“The word went around like wildfire. Mates rushed around to help and Blake calmed Amy down by giving her water before taking her to hospital.”

“He was terrified - but she was a mess. She didn’t know what was going on.”

Amy was taken to hospital in the early hours of Wednesday morning and is believed to have had her stomach pumped and given an adrenalin injection before being released later that day.

The source added: “she thinks all this stuff is romantic. She uses the word ‘Byronic’ - but for everyone else it’s terrifying.”

According to the Mirror, Amy has now checked into the Priory clinic in London, with her dad Mitch & mum Janis at her side.

Speaking to the newspaper about the collapse, Blake’s father, Lance Fielder, added that he’s in no doubt that the “severe exhaustion” line issued by her spokesperson was a cover up: “[Blake] told me he was very worried about her. He admitted they both drank and did drugs but that came as no surprise.”

“It was bought on by all her excesses. Yes, work is one of them, but there’s the drink and drugs too.”

“She’s got to get a grip on herself before it’s too late.”
