Evamist
"After having a serious reaction to the estradiol patch, I switched to Evamist. As the literature states, it may take a few weeks to feel better. I have been on it one month now and feel much better than I did on the patch. I generally get only one hot flash per  day and I can live with that. I had terrible heart palpitations on the patch. They have completely disappeared and I feel human again. To the previous poster that gave a 1 rating, you may have to give it more time. I know when you feel crummy, a few weeks can feel like a lifetime, but using something one week is not enough. See if you can stick with it for a few weeks. My OB told me that you really can't judge how it is working until you have been on it one month. I use three sprays"
