Let's see, I have purchased other products with magnesium for painful menstrual cramps so when I saw this, I just knew I had to have it. Nothing short of amazing! At night I suffer from migraines, a few squirts on the back of my neck and I'm back to sleeping peacefully. I've also sprayed on my stomach during my womanly time and it has eliminated my discomfort. Definitely a staple product for me.
