Overall, I liked Carr's book. It changed my perception of alcohol and motivated me to consider quitting.
However, for me, the main flaw in the book is that it denies that there is any pleasure in drinking (and that we've just been conditioned by society to believe there is). This didn't ring true for me.
The approach that has worked for me is Rational Recovery by Jack Trimpey, which says that, ultimately, the ONLY reason we drink is for the pleasure, although we often give other reasons and excuses. This I could relate to and is quite liberating.
Now I see alcohol as a pleasure that I gladly don't indulge in anymore.
Carr attempts to remove the desire to drink by trying to show how there's no pleasure in it and that by understanding the trap you will be free.
It didn't work for me but he does make some good points and it's worth a read.
