Exercise! You may not want to, but get in your workout anyway. The endorphin rush will help relieve cramps and raise your levels of serotonin, a mood-lifting neurotransmitter.
Get some R&R. Adequate sleep and less stress will put you in a better hormonal position to handle the physiological imbalance that PMS brings.
Cut out most alcohol, caffeine, and salt. Alcohol can exacerbate feelings of depression, so steer clear. Reducing caffeine may minimize breast tenderness and irritability, and cutting salt can reduce bloat.
Minimize simple sugars. Ideally, you're doing this all the time, but it's especially important before your period. Simple sugars may increase inflammation, making cramps worse. Eating regular meals and snacks with fiber and protein will help keep your blood sugar stable, which is a lot better for those raw nerves than blood-sugar swings.
Consider supplements. Calcium may reduce symptoms of PMS, so shoot for at least 1,200 mg a day. Magnesium is also helpful, as are B complex vitamins. To reduce the inflammation of cramps and breast tenderness, try a primrose-oil supplement; it's a nonsteroidal anti-inflammatory that may work in ways similar to ibuprofen.
I sure did need these tips. Let me know, if these help you and which ones. I have been struggling with very bad headaches and tenderness. I will be getting some primrose oil asap.
