Utter trash. I spent many years working with people who had varied problems exaccerbated by their use of alcohol and/or drugs, I've undertaken years of academic research, I've been involved in small scale and major field studies, I've read sophisticated, informed and intelligent analyses of drug and alcohol abuse ... and I've also had to read a lot of books like this trash.
Alcoholism is not a disease, get that straight for a start (read "Problem Drinking" by Heather & Robertson, an excellent, readable account which dismantles the disease model)!
The author, here, comes across as a shouty, loud mouth who wants to be the centre of attention. There is not one shred of reasoned, scientific argument she is able to present. The book simply shouts ME, ME, ME. It is appallingly written, it's disjointed, her arguments are shambolic, it does really advertise her need for attention rather than any rational, coherently argued analysis of the problems people experience in drinking. It's simply ME, ME, ME - shout, shout, shout.
Her 'cure' - follow a diet ... fortunately she can sell you nutritional advice. Now there's a surprise.
Dire. Frankly, if I was ever going to advocate the burning of books, it would be for stuff like this.
