"Throwing out the alcohol is just a waste of money and no more."
I can certainly confirm that. I gave up hunting for AW's hidden bottles some time ago. Our adult daughter still tried it for a while, because she thought she could shame her mom into quitting. All it did was make AW more clever in how she hides it. We suspect now that her drinking buddy is bringing it to her in water bottles when we aren't home, but we're not sure. AW won't admit to anything.
AW has "quit" five or six times, but always returns to the bottle. From what I've read here, some people never stop until it kills them.
I'm really sorry you're going through this, but at least you have some great support here.
