I agree with the statements made, very good advice. I would also like to add this. You and your Husband are not bad people because you don't want that in your house. His drinking problem is not your fault as much as his recovery is not your responsibility. My family told me many years ago that I was not welcome around them while I was still drinking. It took me getting sober to appreciate that. If I was not allowed to hit my bottom, I may still be drinking today. Please don't feel bad for telling your Brother he must leave and not return until he is sober. He may never stop drinking, but you are a good Sister who tried to help, and if he does quit. Chances are that he WILL find work and a place of his own.
About the ugly confrontation, it probably will be unpleasant, but you only have to do it once. Putting it off will only make you suffer longer. My advice is not to wait a minute longer to have your home and peace back. Good luck...
