The Back to Black star, 27, who had fought drug and alcohol problems for years, was discovered lifeless in bed at her North London home on Saturday, July 23.

In June, she had stumbled around the stage during a shambolic concert in Belgrade, Serbia, where she was booed off after slurring through songs.

And as tearful parents Mitch and Janis listened yesterday in the public gallery, the hearing was told Amy did not drink for the first three weeks of July.

But she then hit the bottle days before her death – and the Mirror reported at the time she was spotted necking shots at the Roundhouse venue near her Camden home after dramatically falling off the wagon.

Giving evidence yesterday, her GP Dr Christina Romete said this fitted a pattern in which Amy would abstain from alcohol for weeks, only to drink again. The doctor revealed she warned the star of the many dangers if she kept drinking.

Dr Romete said: “The advice I had given to Amy over a long period of time was verbal and in written form about all the effects alcohol can have on the system, including respiratory depression and death, heart problems, fertility problems and liver problems.”

Amy, who won five Grammy awards in 2008, was taking medication to cope with alcohol withdrawal and anxiety. She was reviewed last year by a psychologist and psychiatrist about her drinking but “had her own views” about treatment.

The GP, who treated her for several years, said her patient fully understood the risks of continuing to drink. Dr Romete said the night before her death, Amy was “tipsy but coherent” and said she did not know if she was going to stop drinking but “she did not want to die”.

Amy had no illegal drugs in her system when she died but police found three empty vodka bottles in her bedroom – two large and one small.

She was using alcohol withdrawal drug Librium and sleeping tablets but the inquest heard they had not played a part in her death.

At St Pancras Coroner’s Court in London, it emerged she had 416mg of alcohol per 100ml of blood in her system, with the legal driving limit being 80mg
