I have this book: Love First: A New Approach to Intervention for Alcoholism and Drug Addiction by Jeff Jay, Debra Jay
It is by far the very best book out there for planning an intervention w/o a professional interventionist. Can be used even if you do plan to use one. Authors are ex-addict and the wife of one who has worked for yrs. in treatment ctr.
They suggest not turning back on our loved ones but instead getting them into the treatment they need.
Excellent book if you are considering an intervention
