Pre-menstrual Syndrome (PMS) What do people think about it?

[LauraStorm]

Hi! Im a 3rd year anthropology student at University College, London (and mumsnet member!)
I am writing a dissertation about PMS and how it affects women's lives and I was wondering if there is anyone living in the London area who would be willing to chat to me or share their ideas?
Thankyou for your help!!

Unless I'm mistaken, there has been research that indicates that seratonin dips for some women around this time. So, surely it IS a physiological thing, that causes physical and psychological problems?
