Liz,
WOW..you are in a tough spot. I can't relate, as I have always been a "social drinker". I'm sure that there is someone out here that might relate and have a better suggestion...however...maybe an intervention by all those that stood by Robin during the fight. There seems to be a bit of self destruction going on here. I can't imagine fighting this fight, dragging all my loved ones along with me thru the mud, and then throwing the experience all away. It is very obvious that you really care for Robin. My friends, family, and doctors would never put up with this behavior. Is your love and caring also allowing you to be enabling. I hate to be so blunt, but I think that my wife would tell me it was either the pub, or our house...my choice. Again, I apologize for being so direct and I am certainly not qualified to give any real direction here, I just know how my caregivers would deal with me. If some swift action isn't taken here you've got to believe that he won't make it. I feel for you.
Rob J.
