I found another article with some tips for PMS in general:
PMS treatment varies between each woman. Each person with PMS is unique, and sometimes it is nearly impossible to predict who will respond to which nutrient, and in what dosage and timing. But, these natural herbs and supplements are worth a try as you discuss these options with your physician. I will update this page as more information becomes available.
Reduce simple carbohydrates such as sugar, fructose, donuts, cakes, pies, cookies, etc. These simple steps are part of a natural PMS remedy.
Reduce caffeine intake, switch to non-caffeinated herbal teas
Exercise frequently, or at least a half hour walk a day.
Vitamin D and Calcium -- Among thousands of 27- to 44-year-old women involved in the ongoing Nurses' Health Study II, those who consumed the most vitamin D and calcium -rich foods had the lowest risk of PMS. Calcium reduces cramping and moodiness -- some patients with PMS have difficulty balancing calcium levels.
Chaste Berry has been shown to improve mood while reducing anger, headache, and breast fullness. Chasteberry is thought to work through balancing prolactin levels.
Consider eating more cold water fish or take fish oil capsules, 3 to 5 in the morning before breakfast, or krill oil.
Take some B vitamins such as B12, B6 or pyridoxal-5-phosphate, once daily in the morning
SAM-e may help some women with PMS. SAM-e is a powerful mood lifter.
5-HTP stabilizes serotonin levels and can be used for PMS as needed. Sometimes it works very quickly, within hours. Since 5-HTP is quick acting, it is worth a try to see whether it reduces PMS symptoms.
St. johnís wort may improve mood, usually one capsule daily, in the morning, a week or two before periods
Magnesium (may help with headache, fluid retention and mood).
Vitamin E may be helpful
Saffron spice may influence serotonin levels and could be beneficial to women with PMS symptoms.
Try yoga, it helps with PMS symptoms, particularly with anxiety and mood reduction.
My daughter tried the extra calcium and B vitamins & said it helped her.
Another article that supports the calcium theory:
The Calcium Connection
Probably the strongest potential PMS helper is calcium. Several studies have suggested that PMS patients tend to have an altered calcium balance and are also at increased risk of osteoporosis. Other studies have linked adequate intakes of milk and calcium with reduced PMS symptoms.
Further, a Turkish study on PMS symptoms in adolescent girls found that higher milk consumption was associated with reduced bloating, cramps, and food cravings.
How much calcium is enough? Some suggest that we should shoot for 1,200 milligrams a day.
This is very doable with foods alone, as long as you like and tolerate dairy products.
And if you don't like dairy? Supplements may help, too.
In a Columbia University study, women with moderate to severe PMS who took two Tums E-X tablets twice a day (for a total of 1,200 milligrams of elemental calcium), showed a 48% reduction in PMS symptoms.
