I don't know if there is a relationship between anxiety and B-12 levels, but there certainly is a link between B-12 levels (and folic acid) and depression. I've read some reports in which psychiatrists recommend people with depression and alcoholics take B-12 supplements/shots, so maybe there is a link between drinking and B-12 depletion. It is also a well documented fact that B-12 is essential in maintaining neurotransmitter balance to prevent depression.
From http://www.clarocet.com/referencelibrary/B-vitamins/ "The National Institute of Health suggests that a deficiency of vitamin B12 can contribute to feelings of stress and anxiety. The link between vitamin b12 deficiency and depression related symptoms has also been demonstrated in clinical studies and case reports involving hundreds of patients."
and from http://www.mts.net/~baumel/B12.html "Columbia University psychiatrist Richard Brown and Baylor University neuropharmacologist Teodoro Bottiglieri (a leader in vitamin/depression research) recommend that all psychiatric patients take a daily megadose of 1 mg of oral B12. In The Way Up From Down, UCLA psychiatrist Priscilla Slagle suggests: "If you are over fifty-five, vegetarian or alcoholic, have extreme fatigue, poor memory, low thyroid or weight loss, I recommend you take 1000 to 2000 mcg of the sublingual form [of B12] every morning."
The point of all of this was that maybe the link between drinking and anxiety is neurotransmitter levels. As a person with Bipolar 1, I can personally tell you that drinking lowers my mood and is probably the worst thing I can do when depressed because it makes me more depressed and keeps me depressed longer.
