you cannot control this. you do not have to give up karaoke or anything you want. perhaps you can go there with friends instead of him? so you do not feel bad about others drinking. and you may enjoy a drink yourself if you wish.
you are not him. its his recovery, not yours. (well, your recovery is about different things!)
its understandable to support him but that does not mean you are "punished" too or your life is ruined or you have to give up anything you like. although i support "being there" and not drinking right infront of him, etc, you also have every right to spend a good time...
you did not cause his drinking
you cannot control it
you will never ever be able to cure him
