The author is a self-help author who has been on the road to recovery from alcoholism.
All you need to stop drinking is a strong will and some important information about addiction. This book contains the condensed knowledge of a "dry" alcoholic and it describes how addiction works and how to stop it. The secret to success is simple to understand and implement.
The only thing you need to accept is the following:
Alcohol addiction is a disease that cannot be cured! However, you must not use it as an alibi.
Never believe in controlled drinking. If you feel the need to control something, you will be controlled by something.
Also, do not switch to non-alcoholic beer, wine, etc., as this will not change your behavior pattern, but will continue to reinforce it. Sooner or later, this ends up back in alcoholic beverages.
Think about it!
