All I know is during the last two months and 1 week I've felt the best I've ever felt in my life. After the first few days it was like my body has been starving for this all it's life. I have more energy, stamina, positive attetude, I now look forward to each day (instead of dreading it), And my left hip pains have subsided a little. Also a very wonderful thing is happening to my hair, -it's coming in thicker and growing fast. I can't wait to see what happens in the next ten months. Being up in age myself (I'm 49, I'll turn 50 this Halloween) hrt has made me feel like I'm in my early 30's again. 😉
