Has been life-changing for me. It has significantly improved my mental health, not just during the intense phases of PMDD before my period. But I actually feel much better during the rest of my cycle, too.

Then in the third month, my PMS symptoms were reduced by 80%! I still have menstrual pain, but the intensity has decreased again a bit.
Moko
