Yes, alcoholics are people too. But it is sadly true that unless a person wants to stop a habit, whether it is drinking too much, using drugs, overeating, or smoking, nothing anyone else can do to help is going to work.
Surely, there must be an alternative to AA? not all alcoholics find their way of helping helpful. As the relative of alcoholics I have always found AA meetings too much of a guilt trip. I can't imagine it helping to be continually reminding oneself that you are an alcoholic.

What about a prescription for Antibus? Yes, I know, you have to be sober when you take it, but for many alcoholics the knowledge that they CAN'T take a drink without becoming violently ill, is helpful.
If or when the person drinking too much wants to stop, then you can and should help, by making sure there is no alcohol in the house and generally avoiding places where it is readily available, which unfortunately is pretty much everywhere these days. It is hard helping an alcoholic who wants to stay off the drink, but it is worthwhile, but until he or she makes the decision, you will only wear yourself out to no good purpose.
