I was diagnosed with PMDD over a decade ago. I kept a detailed journal of my moods, and it was clear that I went off the rails around the end of each month, about a week or so before my period. Literally EVERY time I got fired for being insubordinate, broke up with a guy, got a speeding ticket, or failed an important test --- it was around the 28th! Hahaha. My doctor suggested "chaste tree" pills. I have been taking them for a long time, and they seem to help a little bit. You can find them at health food stores or online. Here's a link to read up on it: Chaste Tree Uses, Benefits & Dosage - Drugs.com Herbal Database.
