I have heard of it... but IMO it is another reason to get you to take another pill. I mean women already have a bad rap for having bad cases of PMS. Some get it worse than others. I read up on it and it is just what I was taught was my normal PMS, just it seems not all women get it this bad which surprised me. It sucks and men normally take cover, so nothing new except what they call it this week. I have had some so bad that I truly understood how a woman could use it as a reason/excuse for murder. I saw it used once. But who was it that did it so way back then ... hundreds of years ago? I think it was in Rome (could be mistaken but think it was Rome) the women went off for days and worshiped some God (my brain is not having a good day so maybe someone will have a better grasp on history) drank a lot of wine. The whole ritual was because she was "possessed" or something like that and went to invite it by this other God instead? Apparently us being very bitchy and evil creatures that scared the men is not new! Just we don't get sent out to go on a binge for a few days until we get over it LOL.
