Yep it's normal. But it can be improved. Carefully watch your diet. Salt causes water retention and the water retention can build up in brain cells and cause you to have little control of your temper. So it may help you to read every lable of every food item you put in your mouth. All the time -- not just a week or so before your period. If a food item has a high sodium content, don't eat it. Learn to eat a low sodium and you may see a lot of improvement in your behavior.
