Dear Annie: You have had several letters recently about people who drink too much.

I have been doing some research on the subject since my niece died several weeks ago of organ failure after years of drinking. She would not take the advice of anyone, but now her problems are over.

The best thing I’ve found is some research done by William Porter, a British solicitor (lawyer) who quit drinking seven years ago.

He has written several books on the subject of alcohol. His site is http://www.alcoholexplained.com. The first five chapters of his book “Alcohol Explained” can be read free online.

Once you read what alcohol does to your brain, you will never touch it again. He has several other books and videos. All are very thought-provoking. — Carolyn A.

Dear Carolyn: I am so sorry that this insidious disease claimed the life of your niece.

I read the five chapters available online of “Alcohol Explained.”

As you noted, the author is a lawyer, not a doctor, but he offers a plain-spoken, useful overview of the chemical workings behind the disease of alcoholism.

I don’t share the view of Alcoholics Anonymous that he conveys in the introduction. However, I do know that some folks struggling with problematic drinking would like options besides AA, and self-education through books such as these can be helpful. (Other good options include Families Anonymous and LifeRing Secular Recovery.)
