Since he's not a traditional alcoholic...
There's no such thing as a 'traditional' alcoholic. It's not WHAT you drink or HOW MUCH or HOW OFTEN, it's what happens when you drink. Sounds like he's in a bad way, especially if he's driving drunk. One accident and his/your whole life can be changed in an instant, and not for the better.
Please do check out the F and F forum. Lots of support and information there.
