Do you have raging stabby PMS that makes you feel like your ovaries are trying to burst out of your stomach like that creature in Alien? It might be because your nervous system is depressed. New findings from the journal BioPsychoSocial Medicine showed that people with the most "marked" PMS symptoms (known as premenstrual dysphoric disorder) "had lower rates of nerve activity than the [control] groups during the entire menstrual cycle." Unfortch for those who come down with the monthly psycho bitchies, there is currently no universal cure for PMDD. [Science Daily]
