He is best going to A&E and they can detox him. you have a big heart, but it's not that simple. I had someone staying with me who was going through the same. The only way he could get help was going to therapy and staying as in patient. Otherwise we'd have to watch him 24/7. He's sneak out, buy vodka, go to the park, get picked up by ambulance, go to hospital, escape hospital and the cycle would continue. Really, with alcoholics, they need more than one on one support. More concerned he's on his won, where's his family?
