Education is critical, but more critical is talking with your daughter -- real communication. Let her talk. Don't preach. What does she say? Listen, pay attention to what she is saying. Accept it without judgment. I would suggest that you then have a drug and alcohol assessment done on her. The school can help you set one up. Let her know that you are doing this to rule out the possibility of abuse and that, if there is a problem, she can receive the help she needs. Follow the assessor's recommendations.
If your daughter did take the wine over, if she does have a problem, continue to love and respect her and keep in mind that she is not her behavior. It is her behavior that you want changed and she is and always will be your daughter.
