Forty-seven-year-old Michael Stenning, who spent three weeks at the Royal Sussex County Hospital in Brighton, began drinking more than four litres of cider a day after losing his job as a courier.
His friends convinced him to seek medical attention after his skin began to change colour.
Doctors at the hospital were "amazed" to see that he was still surviving.
"It was a miracle. I have never seen someone as sick as him leave the hospital alive," the Telegraph quoted Dr. Sumita Verma, who researches alcoholic hepatitis, as saying.
Stenning, a father-of-two, said: "I am a miracle case and just so happy to still be alive. I am touched by the continuous support from my family and friends especially after how I treated them at the time."
He revealed that he stopped drinking only when he was warned that he was about to die.
"I now want to make up for the years I've lost while drunk," he said.
He further said that his skin had begun to return to its natural colour since stopping drinking.
"Staying off the booze has been easier than I thought and I'm happier drinking non-alcoholic drinks, which complement my now healthier diet. I have even started an exercise regime," he added.
Stenning, who is divorced, credited his two children-Matthew, 22, and Sophie, 19-for supporting him in his struggled with his alcohol addiction.
"They really helped me through it all. I can't thank everyone enough. When they noticed I was turning orange it was the last straw. I had to do something," he said.
He said that he owed his life to the staff at the Royal Sussex County Hospital who helped him beat his addiction.
Stephen Leggett, who alerted Stenning when his face began to change colour, praised his friend's resilience.
"A lot of people relapse, but Mick has stayed so strong," Leggett said.
