    Massive difference to my periods. They are still every 2 weeks, but last 7 days instead of 10, a lot lighter, no fluid retention and no symptoms except mild the day before my period commences. I take two on an evening with evening primrose oil. Highly recommend.

    took around three weeks for my anxiety to lessen but by day 2 I was sleeping better. There are still occasional not so good days/night but what a change this has brought to my life and so quick than the usual antidepressants with no side effects at all. I would recommend this to anyone and everyone.
