As a loving mother concerned for her family, I highly encourage you to investigate what I and others had to learn the hard way. As a young man,I loved(craved) my beer.
I am convinced that alcoholism does not run in your family. What I strongly believe does run in your family, as well as many other families, is systemic(or chronic) yeast infections. It is known as one of the "hidden epidemics".
I was raised by my WWII Nurse mother on prolific amounts of antibiotics, introduced as a miracle cure by the Dr's she worked with.
Antibiotics kills healthy flora in one's gut which becomes replaced with candida(yeast) or candida albicans. Everyone knows when you mix yeast with any sugar product you produce alcohol. A lot of children have low levels of alcohol in their blood which I believe is being misdiagnosed as ADHD.
Do a google search for "yeast + ADHD"
Here is an attorney who actually documented a DUI(yeast infected blood) specimen that fermented in the test tube that raised the test results above legal limit.

Children can easily be infected from the mother during birth. If the mother is suffering from vaginal yeast infections,when a child is born, the child's mouth scrapes the lining of the vagina. Instead of receiving a dose of healthy flora it receives an unhealthy dose of yeast. This is why alcoholism seems to be generational.
A lot of women who have "recurring" vaginal yeast infections are actually infected in their colon and due to the thin membrane between the two, yeast makes it's way into the vagina easily(why it is recurring).
Once I understood this parasite and how it affects our body I no longer "crave" alcohol. I can have one beer, enjoy it immensely, and be done.
As a protective mom, keep you son healthy is the best option. I can assure you he won't turn into an alcoholic.

Many other health issues can be related to this infection to include cancer.
Do your own due diligence in researching this matter and ignore the naysayers. Some more good google searches, Here is one interesting connection.
