there are alot of factors involved:Age,sex etc..
and wether they are still drinking and what they are drinking.
we had a female friend who died from this. she drank herself to death, with beer. had a husband and kids in grade school.
not only were her eyes yellow, but she was yellow.orange. i was shocked when i saw how bad she had gotten. this was 20 years ago. she would not stop drinking.
although no one can predict when it will kill someone..she lived about 6 months. it was so sad. her daughter thought her mom didn't love her enough to quit drinking.
i am so sorry you have this to deal with.
