Hi Raimi.....As far as your question regarding Progesterone usage I think you should discuss that with your physician or health care practitioner. I am so pleased to read that you are trying Revival. I have been using it since last August and it has made such a huge difference for me. It has virtually, single handedly, eliminated hot flashes, night sweats, sleeping issues, waning energy, high anxiety and aches & pains. I know it sounds too good to be true but these claims are factual. I also realize that not all of the women who use Revival have this degree of success however they do feel the rewards of using Revival soy. My physician is very pleased that I decided to use soy as an alternative to HRT and was especially pleased with Revival. Also Evening Primrose Oil is excellent in reducing hot flashes. This site has an awesome "Recommendations" section. I suggest that you go there and read the list of vitamins, herbs, other supplements that Dearest has listed. She is forever updating the information and its the best advice/suggestions you will get anywhere.Hope you enjoy your Revival as much as I do.

Blessings and be well.
