Increase your intake of Magensium a little. Try not to panic!

Magnesium throughout the day (per @Greg Sacramento ), NAC, curcumin, green tea, Nicotinamide Riboside all aren't bad.
I totally swear by liquid magnesium chloride (make sure it's the oral kind not the topical) over other magnesium. Tastes terrible but seems to be much better absorbed.
