I am 71 years old and still suffer from hot flashes, mostly at night. I have been on estriol since I have been 42 years old. I stopped using it last August, 2013 as I wanted to see if I would still suffer. I do, and I just want to take a drop of estriol a day, that is all I really need. I want to know if there is something I can get that would be like that. I have tried Black Cohosh, essential oils, and right now Amberen. Nothing helps me, just the estriol.
