all I know is that when I start crying while I"m watching friends I know another month has come and time to start taking ibuprofren like it's candy...
All my clothes don't fit right and I get zits and feel overly hot or overly cold or both in waves for the first day or two... Legs are weak and I've no energy for anything and everything I say or do seems to be completely irrationally wrong with no way for me to make it right.. it's best on a day off so I can just hide for the first day or two until everything is cool again..

BUt OH WHen the period is OVER!! WOW I am so happy.. birds are singing and everything is amazingly wonderful...
