I've heard of that happening, yes. I'm not sure how it works. Opivy is right about the link between B12 and depression; I would assume a similar link between B12 and anxiety, and of course alcohol probably similarly interferes with other nutritient absorption which may impact anxiety. But not really sure how it works. I can't say I've noticed this effect from alcohol in myself to a significant degree.

I do know that if you are taking certain medications for anxiety or related disorders like depression, alcohol can interfere with its absorption and so should be limited.
