Really bad PMS - home remedies?

Does anyone else get PMS really bad? I'm on the hormone free IUD and I get unmanageable PMS symptoms. Cramping is so bad I'm incapacitated for at least one day and need something to squeeze because they literally make me tear up with pain. I become very antisocial and feel angry when strangers even look in my direction. I'm lethargic, my skin gets dry, and I barely have an appetite, but only crave junk food. Does anyone know any remedies besides pamprin/midol/pain killers?
