I say hammer them to the wall. 4 game suspension on conviction. It doubles every subsequent conviction.
I had a policy of 'if I am going out drinking' then I do not bring my car. You can condition yourself mentally that you are going to give up your keys no matter what BEFORE you start drinking to avoid machismo stupidity. I don't drink anymore because it's not fun for me but there is absolutely no excuse for this. None whatsoever.
