and I've decided to dedicate this post to aisling to say thanks. I'll quote her because I think this is cool enough that everyone should know it:
(Usual disclaimer: I'm not a doctor & this is anecdotal, not medical advice, blah, blah.)
Anxiety after drinking is often related to how alcohol depletes your vitamins B & C. Especially the Bs, which help to calm raw nerves. If you're drinking beer, this is particularly true, since vits B & C are water soluble.
So, when you get up in the morning, pop at least a stress-type-dose vitamin B (with food or lots of water/juice), and a chewable C is a good idea as well.
