Sorry to hear what you are going through, and please don't forget to look after yourself first. Unless he decides for himself to stop the madness, you are dealing with someone who will chose drink over anything else, no matter what the cost, and will continue to do so. The sad thing is that it isn't even "personal" - it's where a lot of us end up after years of alcohol abuse.
