I found that Red Clover and Black Cohosh worked great for me; others get a lot of good out of chasteberry or evening primrose oil. You may have to just try a couple different things.

I didn't know it when I needed it, but caffeine in coffee and sodas can make pms worse.
This time, like all times, is a very good one, if we but know what to do with it. Ralph Waldo Emerson
Any given day you are surrounded by 10,000 idiots. Lao Tsu, founder of Taoism
