hi linda, i started using serenity progesterone cream a while back, im on my third month. i am going slowly because at first it made me even more moody and irritable so i really only put on a tiny amount to build up. im on the normal dose now and this month havnt felt moody and my boobs werent quite so sore so its working. I havnt got that fearful feeling much now so im pretty sure my hormones are way out and that is my problem. my periods are only 1 day, every 21 days, so im sure im going through the menopause, last year my period was every 28 days for 6 days and very heavy. i use my cream on the 10th day of my cycle until my period, even young girls can use it. it doesnt make me sleep, i wish it did. i think its well worth a go. i had all the symptoms of estrogen dominance so i didnt bother to get tested, in the end i spent the money on the cream and very glad i did so. I have read lots of books on the subject just lately and they all recommend progesterone cream.
