After an enlightening talk with miss JL (not myself), we agreed that i would post THIS!
Muah haha. Take a goooooooood read, my dear male friends.
Taken from Wikipedia:
"PMS is a collection of symptoms. More than 200 different symptoms have been identified, but the three most prominent symptoms are irritability, tension, and dysphoria (unhappiness). The exact symptoms and their intensity vary from woman to woman. Most women with premenstrual syndrome experience only a few of the problems.
Constipation and possible hemorrhoids due to water retention
Breast tenderness or swelling
Itching of the breasts
Stress or anxiety
Appetite changes and food cravings
High sexual arousal or desire
Trouble falling asleep (insomnia)
Joint or muscle pain
Body temperature increase
Worsening of existing skin disorders, and respiratory (eg, allergies, infection) or eye (eg, visual disturbances, conjunctivitis) problems "
Methinks that you can now sort of figure out now why we tear people apart during a certain time in a month.
