Query: Helped a lot

This book will give the reader an excellent understanding of the differences between social alcohol use, alcohol abuse and alcoholism. It includes a simple experiment one can try on oneself if they think they might have an alcohol problem.Easy reading and very well explained. This book and the self experiment helped my friend to realize that he had a serious problem with alcohol and to get into recovery. He has now been sober 18 years!!!Highly recommended reading to a person with a drinking problem or for someone that is concerned about another person's drinking. Two Thumbs Up!!! Thank you Dr. Keller and LGH!!!
