On her next binge, change the locks to the house and make a police report. Give details as to how long the children have been living with you and you are their primary care giver.
You could call Child Protective Services and ask what your options are, and that you don't want to lose the children, but protect them. Don't give your name right away.
Or confront your daughter and tell her you will turn her in if she tries to leave with the kids and that you want her to sign guardianship over to you. Don't let her take you prisoner. You end up being her enabler. Stop and take control right now.
