Thats a hard situation hun and I fully feel for you! I've been in a somewhat similar situation and I think practicing some tough love and removing you and your son from the relationship (using legal means if necessary) until he gets treated is the best all round decision since his drinking and bad behaviour affects you all negatively. Sometimes we have to make the most painful decisions to make things right don't we?! \
ETA I personally wouldn't give him unsupervised access while he is a 'practising' alcoholic. While you may feel guilty about withholding parent privileges from him just remember that he created this situation and he's responsible for consequences, not you.
I used legal aid btw and I had an awesome lawyer from a topnotch firm. You can ring round and find out who does legal aid and who is available and go with who you feel most comfortable with.
Hope it all works out
