Drink Less Alcohol
Most experts believe that drinking in moderation is not harmful and may even have health benefits, but for women with PMS, alcohol may do more harm than good.
There's evidence that drinking red wine offers cardiovascular protection, possibly from compounds contained in the grape skins used to make red wine, and there's also evidence that moderate drinking strengthens bones and is associated with a lower risk of developing kidney stones and a lower risk of diabetes.
But alcohol, a depressant, worsens PMS symptoms, especially mood symptoms and can drain your energy level. It may also increase your risk for painful cramping during your period. Ironically, the premenstrual phase may be the time when you are most sensitive to alcohol's effects: progesterone, which drops during the luteal phase, may affect your alcohol tolerance.
There appears to be a mutually negative relationship between alcohol use and PMS: having PMDD (and other affective disorders) is a risk factor for alcohol abuse in women, while alcohol abuse risk factor for PMS.
A number of studies have looked at PMS and alcohol; suggest that women with PMS tend to drink more than without PMS. It may be because the women’s PMS symptoms enough that they use alcohol as a coping mechanism, or it something else entirely.
