My father drank about as much as you, and he nearly died of liver chirrosis. Which would have been extremely painfull. He died later, after not drinking so much, of heart failure. The medical examination showed he had escaped chirrosis by an inch.
My mother drank way more than that. Eventually her state deteriorated, she went to a psychosis and she soon died. Only after death we discovered she had had pancreatic cancer. So it was good thing, in a way, she passed quickly, not prolonging her agony. Because death by pancreatic cancer is a really painfull way to go. See a pattern? She started soiling her sheets soon before the psychosis. And, her last month she mostly could not communicate, as as far as I can tell, she trembled in fear in her bed.
Was the fear because of psychosis? Or had the hospital staff maltreated her, because, you know, she was just a psychotic fragile drunk? I will never know. She was 66 when she died.
As I understand she took to drink in a major way in her late twenties, and never gave up. She became depressed and lost her job, and drank more.
Some people drink to their grave in the nineties, and stay seemingly healthy, so, it's a game of chance.
Look up alcohilism and it's complications. The bad thing about most of them, is that they creep in, and when they are obvious, it's likely too late to do anything and it's a slide to body horror land and gruesome death.
I know scaring people doesn't work, but at least you have some concept of the odds you are dealing with.
Take care, man.
