from the Scottish newspaper, The Daily Record (12/06/06):

MIGRAINE sufferers have a bigger sex drive than those with ordinary headaches, according to research.

A study found sufferers reported a sex drive 20 per cent higher than those who experienced tension headaches. American university researcher Timothy Houle said: "Our study suggests sexual desire and migraines may be influenced by the same brain chemical."

Ah, another one of those health-study articles with very little information in it...like other research on the same area, how was the study conducted, sample size, measurement methods etc.
