75% of women live through PMS each month feeling bloated, agitated and crampy.
Lindsay does not just deal with PMS.
She has PMDD, premenstrual dysphoric disorder.

Samantha Meltzer-Brody, M.D., University of North Carolina said, "We're realizing a lot of women have suffered silently for a long time with these symptoms."
Other signs are weepiness, anxiety, tension, night sweats, muscle aches, and pains.
Severe bloating and tenderness, headaches and overeating are also common.

Treatment includes low doses of Prozac when ovulation starts.
Higher doses of calcium foliate, magnesium, primrose oil, and mega fatty acids have also been shown to work.
