I also have horrible menstral cycles ! It starts a week before my actual period comes. I get real sick. I am on promethazine for my upset stomach 2 weeks out of the month just because of my period, thats not including my Apriso for CD & my normal medication. I do have to take a lot of midol these days also. It is awful. Try to give her MIDOL COMPLETE the white ones that seems to help with the worse cramping, body aches, stomach issues. Its worth a try.
