The Allen Carr book is great for readjusting your perception of the so-called benefits of alcohol. For me, it never worked long term but if you use Allen Carr's EasyWay as your moral reason for making a Big Plan and AVRT to implement it I cannot see how anyone can fail.
In an ideal world I think a complete book that combines The Easy Way to Stop Drinking/Control Alcohol with Part II of RR:TNC would make a very potent manuscript.
