I read somewhere that getting more sleep and cutting back on alcohol can help PMS. Otherwise, I would suggest taking some kind of medication advised by your doctor or taking birth control pills as Mistress Florence suggested. One of the reasons my Master put me on the pill had to do with the things described in this topic. The thing with the pill though is that it can cause other side effects of its own, which is why I had to stop taking it for awhile. I'm back on it now and things are fine, so that may be one option for you as well.
