Geppster, welcome to SR!
Going to Al-Anon is for us; because alcoholism is a family disease and we are all affected by it. Your kids may even be interested in Ala-Teen. They carry the same scars you do, in their own way.
Posting here and going to Al-Anon are great first steps. It allows us to slowly walk toward our own solutions, instead of trying to force solutions that may not be to our benefit. I can guarantee the problems here are much deeper than just putting the bottle down. Take it all one day at a time. Decide not to engage in his drunken arguments. And possibly try a bucket next to the bed?!
Keep posting and keep coming back!
