Diet plays a significant role in PMS. Certain foods, especially junk food, tends to aggravate PMS. I've noticed that when I eat healthier during days leading up to my period.....my PMS is not severe.....at times it seems like it's not there. I've also found that regularity in prayer, exercise, taking a multivitamin/iron supplement also make a considerable positive difference:)
^ i second that.
it works for me...not sure about others tho.
