If it's not genetic than nurture plays a far greater role than I thought. A person with an alcoholic parent is about 50% to have a problem and even more with 2. Add in other nurture classifications like abuse, lack of support etc and your chances continue to rise.
Ultimately however if you don't own a problem it's going to be far harder if not impossible to address. In that regard I just remind myself that no one ever tied me down and made me drink so this is my problem, my life and I'm the solution.
