Ever since a somewhat spectacular head injury I have been troubled with regular migraine headaches. As every sufferer will tell you - they're something of a pest.
A kindly neurologist has given me access to gratis Zolmitripan - an expensive drug of rapid and complete effectiveness. One is somewhat wary of it's side effects - which unfortunately include the absence of the drug becoming a trigger for headaches.
But lo! After some internettery I found that some people use the most delightful and unexpected preventative measure. After protracted trials I can now publish the fact that - for me - dark chocolate stops nascent migraines. Woo and hoo!
