I found this while on a website about addiction in the family today:
Children of Alcoholics
According to the National Association for Children of Alcoholics, 18 percent of American adults grew up with an alcoholic in their home while almost half (43 percent) have dealt with an alcoholic in the family. Alcoholism is four times more likely to develop in children of alcoholics than in other families
Thought I would share. Both of my parents drink. My dad at 8 beers a day yet when I tried to talk about it once he got mad.
