You didn't say whether you'd tried any herbal supplements for your period. Assuming your doctor agrees, I think you might want to try Magnesium (relaxant), Fish Oil, and Chaste Tree Berry. It may take two cycles to see the effects. You can do a high dose of fish oil for bipolar disorder because it has mood stabilizing effects.
Also, drink LOTS of water, reduce sodium, alcohol and caffeine, and try to exercise by at least walking 15min every day during during the days of your cycle when you'd typically have symptoms. Plan ahead for this!
If you want something more "big guns," you might ask your p-doc for Valium to take during your cycle. It is both a sedative and muscle relaxant. I noticed that you aren't sleeping during your period and am surprised you weren't prescribed a benzo.
