I had a very similar experience up until this past month.

Since I started low carbing (labour day weekend) my physical PMS symptoms diminished, however, the inner bitch really let loose. It was quite frightening. I'm happy to report though, this past month I was running at only about 20% bitch. I hope this change is here to stay.

In the health concerns part of the forum, I started a thread "Womens PMS experience on low carb" perhaps you could look it up. I religeously take UDO oil (an essential oil supplement) and have been eating more macadamias lately. Who knows? In the meantime, might I suggest you find something to beat the crap out of? I have a 100lb heavy bag in my basement.

Best of luck!
