Long time sufferer, until...
I suffered terribly from the age of 11, cramping, throwing up the whole bit. Had an ultrasound, no reason for it. Went on the pill at 17 and still no relief. Tried the Annaprox, complete waste of time. And then some kind angel suggested I try a Chinese herb called Dang Quoi (there are several spellings). It smells terrible, comes in capsule format and has been my saving grace for many years now. I take it for about 3 days before and 1-2 days during and I am fine. Absolutely NO cramping, throwing up nothing. Please, before you stick her on the pill go to your pharmacy or local health food store and try this. There is NO guarantee the pill will work, it didn't for me.
