my grandfather was an alcoholic on mom's side, and she was a true blue co-dependent. My grandmother raged at him - i took after her! My father is an alcoholic, and i think he is in denial about his dad, because that side of the family sure do act out the alcoholic/codependent drama. His mother never drank though.
I married an alcoholic. So my kids probably have quadruple the genetics to be alcoholics. their genes probably have little beer pitchers all over them just waiting for the big event. I have tried to not be evangelical about it -but do tell them that they may have an extreme "allergic reaction" to alcohol which may get them hooked from the start, so they might be better off avoiding it. I am hoping that by growing in my recovery that i will be able to furnish them the coping tools they will need in their adult life so that they won't need to fall back on such a wicked crutch.
