I believe in it.
With three sisters and a best friend who do suffer with it, I'm fully aware of how much it changes someone.

You can no more exert any conscious control with it than you can when you're drunk.

My best friend used to get really nasty and was mortified with herself afterwards for some of the things she said.

This may be somethig different . . .
if your friend can't remember what she's done, it may not be garden-variety PMS. I have vague recollections of a disorder we were taught in Psychiatry - a form of hormone-induced psychosis. If that's the case, it's a very different beast . . . and real.

She remembers everything.
She just can't understand why she would say those things.

Quick check of the symptoms . . .
there are a slew of names for this . . . and it's not common.
It's actually a spectrum of disorders - bugger, I'm not at home to look up my old textbooks.
Have a link:
en.wikipedia.org/wiki/PMDD
The list of symptoms is interesting. Maybe seeing someone who knows more about it than I do (undergraduate Psychiatry) could be useful.
