A great tool for anyone who teaches about alcohol. Also a great read for anyone who uses alcohol. Not preachy in the slightest. Includes detailed scientific information on the negative (and some positive) effects of alcohol on the body. A divergence from the "all or nothing" approach so many take to alcohol. This is the only self help book that I've ever heard of that has completed a full study on folks who've used its tools and strategies, then published a second edition with results from the study and tweaks based on what worked and what didn't. I got it at the library, and though I almost always prefer to support public libraries, I wish I had purchased this book (and still might). There are a lot of concrete workbook-like exercises and quizzes that will be easier if you can write in the book.
