Bless your heart! Yes, that is what they do and that's what he will keep doing regardless of whether you pour out the alcohol at home, confront him about it, your family is broke -- doesn't matter. I remember when I use to do those things. Praise God I don't anymore! It will drive you crazy trying to find the hidden bottles or whatever tricks you try to prevent the A from drinking. These things accomplish one thing and one thing only, driving you mad.
I echo what others have said, please focus on your own well being by attending Alanon or seeking therapy if you can afford it. It will give you the tools you need to maintain peace of mind.
Hugs!!
