I am taking Vivelle .025mg patch, 2 patches twice a week, and Prometrium every three months for 10 days. LIFESAVERS! I had the gamut of perimenopause symptoms and more - night sweats, insomnia, ringing in ears, dizziness and balance issues, fogginess or inability to concentrate, anxiety and even panic attacks, tingly fingertips, blood pressure spikes. All of these were eliminated or reduced when I went on HRT. I was able to stop take my meds that I was taking to sleep at night. I was able to stop taking anxiety meds. Hallelujah! It will be 1 year on HRT next month, and I cannot imagine what it would have been like without it!
