I tend to overreact to pretty much everything when I have PMS. What can I do to prevent this?

Here's a good strategy that works during PMS or anytime you're stressed: Whether it's your boss, your husband, your kid or burly men carrying a straightjacket with your name on it, take a deep breath before you respond! It's guaranteed to calm you down. Plan ahead to protect yourself and your loved ones by taking charge of your health–both mental and physical. Choosing a healthy diet, supplements and getting some exercise* can send your PMS packing. At the very least, it will minimize the effects and maximize your wellbeing.

*Chucking china, pitching fits and hurling ultimatums doesn't count as exercise.
