muffinyou have 15sober days fantastic,you need never drink again.
My Mother was an Alcoholic,she developed a wet brain before she died,I know many sober people who had Alcoholic parents.I was 55 when I got sober,I have a friend who was 78,he has had 20 sober years and still going strong.
Early recovery is not easy but has to be got through without taking a drink,then it gets better.
I wish you well.
