No, there is no way you can force him to get help. And there is no way you can force your mother to stop enabling him.

Is there a second bathroom in the house? If there is, then start using that bathroom, and don't even go in the bathroom your brother uses . . . not to clean it, not to use it . . . make believe it doesn't exist. Your mother is enabling this situation. Let her worry about the vomit-covered bathroom.

Does your mother need financial help from your brother to keep a roof over her head? If the answer is "yes," then that's the trade-off between them. She puts up with the drunkeness because he pays room-and-board. She'ld probably put up with it, even if he lost his job. Change is unlikely. The two of them will eventually be going down the tubes together.

Where does this leave you? You really have no obligation to clean up your brother's puke no matter what, IMHO. Even aside from the puke, that's got to be a miserable place to call home.

You might want to take in a meeting at Al-Anon. Get some of their literature. They helped me enormously to see an important truth of life: What other people do is their business. Your focus should be on what is your business. If you're in a miserable environment - which you are - work on a plan to get yourself out of that environment. Until then, keep up a wall between how your brother lives and how you live, as much as possible.

Are you past the age of 18? Are you working, or going to school? Do you have an income? What is your plan for your life? Focus on that like a laser.

Your brother, obviously, is a mess. Keep thinking: "My brother is a mess." and, eventually, you'll be a mess. Decide, right now, that there's a limit to how many minutes of the day you are going to spend thinking about your brother. I'ld set that at about 2 minutes a day. Spend the rest of your waking time thinking, "How do I get out of this crap-hole I'm living in . . . that is only going to get crappier, as time goes by?"

By the way . . . your brother is not a kid.
