Alcoholism and life expectancy?

my husband has been drinking on average 7-8 measures of scotch each day for the past 10-15 years, although I dont see him drink as he is very secretive. He has currently got hypertension, kidney stones (with a stent and is experiencing bleeding), high cholesterol. He may be borderline on diabetes. He experiences mood swings and memory loss. I have evidence that he buys 2 bottles of scotch every 2-3 days and has been doing so for at least the past 5 years, he is 53. I am wondering how long he may live at this rate?
