Boiron Homeopathic pellets - the ones for "menstrual cramps". You can get them at Whole Foods or Vitamin Shoppe. I've had terrible menstrual cramps since I was a teen. This stuff completely prevents the cramps. I thought it was maybe all in my head, a placebo effect. But my SIL, who suffers even worse cramps than me, tried them and they worked for her, too!
