It's got so much worse in the last two years. I'm 39 now.
For three days before, I'm extremely irritable, ratty and on the actual day it arrives, the anger I feel is just extraordinary. Then it arrives and I think, "Oh of course!" every time and I'm back to normal in a flash.
I think my family suffers. I know they do. It's not good.
Can anyone suggest anything that they've found alleviates it? I can't keep breeding to stave off periods! 
But I also can't take oil based products because I get very spotty with them.
