Respectfully, I disagree. P could have used this tool. As I said, it took him several years of living with me to understand that the mood changes (swing is such a mild word for some of it) were pretty predictable and there was a reason for it. He just thought I periodically became a raving bitch for no reason.

And trust me, me on PMS does in fact equal raving bitch queen. I spend most of my time wanting the rest of the planet to get the hell out of my way, if I'm not actively planning on helping them.
