Husband is a alcoholic

So my husband is a alcoholic and he told me that before our baby is born he would cut back or be done with it all together. I know that I might be over reacting but instead of slowing down it seems like he is drinking more and more each day. He is spending any where from $11 - $22 a day just on beer. Not to mention cigarettes. To me I feel like his alcohol is more important than saving money for when the baby comes. Please help me what should I do?
