LADIES ONLY! Estroven for PMS?

I visited my gyne today to check some lumps. And we got to talking about PMS. Since I gave up all caffiene and cut back on sugar, I no longer suffer from the painful menstrual cramps, breast tenderness and mood swings that I had before. Life is so different! Much better!

But I still get migraines--they last for 2 or 3 days and no amount of over-the-counter pain reliever resolves them. They can be blinding and occasionally they are so bad that I just cannot function. They suddenly come right before my period and suddenly leave a couple days later.

The gyne suggested I take Black Cohosh and Soy (the ingredients in Estroven) a few days before my period starts and a few days after it starts. She said the estrogen level in our bodies causes much of our PMS symptoms, and the Estroven helps even it out a little.

I'm not a pill taker. I can't remember to take pills everyday for months or years. But she said I only need to take the Estroven just for those few days--not the entire month, just during the periods of low estrogen.

Have y'all tried this? I thought estroven was for menopause, but here's a new use for it. Do any of y'all take Black Cohosh and Soy in some other form? How often do you take it? Any side effects?
