We have always told our daughter that if she finds herself in a situation and needs to call us to come get her, we would come, any time, day or night.  We thought we have been vigilant parents, making sure that she has not been drinking or using drugs when she is out with friends, and certainly not when she is driving.  The other night, though, she called us at 10:30 and told us that she was not feeling well and need to be picked up, even though she had driven herself out to "bowling" with friends that night.  She immediately admitted she had been drinking and could not drive.  We immediately left and picked her up--found her feeling very sick and having thrown up.  We were so glad that she called.  She had driven her car, however, a short distance before stopping at a gas station. 

Now I have come to learn that she has been drinking when she is out with friends for quite some time (a year or two).  She is never falling down drunk when she comes home--in fact, we have never known that she has been drinking.  She has also been driving after drinking.

So, what do we do now?  I have told her that we are purchasing a breathlyzer that we will use every time she goes out and that we will randomly drug test her.  My husband wants to install an ignition breathalyzer in her car.

For what it's worth, she is an excellent student, with lots of friends, sports, and activities.  None of this has affected his school work.  As I said, we knew nothing of it.  I don't think it is practical or even advisable to put her on total lockdown.  I just want her to be safe and make smarter decisions in life.  Help.
