How to tell children about alcohol

If I have children, I want to tell how dinking alcohol is bad to my children. First, I want to tell them drinking alcohol can make big trouble, because alcohol can make us confused when we drink a lot. So we cannot remember something we did, and sometimes we cannot control our mind and do something ugly or worse. Second, drinking too much alcohol is not good for us. It makes us get heart disease and some other disease. It is too bad for our health. Last, I think I should tell my children that alcohol costs too much money and the smell is not good. Drinking alcohol can make us fail in our job, have a broken marriage and some other bad things.
