A condition where women, before their period, experience these symptoms:

A- Anxiety: irritable, crying without reason, verbally and sometimes physically abuse, feeling "out of control", or Dr. Jekyl-Mr. Hyde behavior changes.

D- Depression: confused, clumsy, forgetful, withdrawn, fearful, paranoid, suicidal thoughts and rarely suicidal actions.

C- Cravings: food cravings, usually for sweets or chocolate; dairy products including cheese, and on occasion, alcohol or food in general.

H- Heaviness or Headache: Fluid retention leading to headache, breast tenderness, abdominal bloating and weight gain.

But not as many women as people believe have PMS. Sometimes people are just bitchy because things are happening in their lives. But with all those symptoms, it's hard not to feel crappy and mean, no?
PMS is no excuse to be a bitch. Suck it up.
