Welcome to SR. I'd encourage you to read around the forum, read the postings and stories, and get acquainted with alcoholism's many faces. But especially, I'd encourage you to read the Sticky posts at the very top of the forum's first page. There is a lot of supportive information there so you really know the enemy you're dealing with.
I agree with the above poster who asked why you would want to find bottles, and what you'd do if you found them.
With alcoholics, you can find the bottles, empty the bottles, berate them about found bottles, smash bottles, get into fights about bottles.....but that doesn't keep them from drinking.
The only question is whether you want to live with someone you know is an active alcoholic, and what you're willing to do to protect yourself.
Wishing you luck and peace
