For hot flashes, I eat 2 tablespoons of "freshly ground" flax seeds every day, usually mixed in oatmeal or other foods. It must be ground and consumed fresh daily. I've tried so many times to skip the flax seeds and the hot flashes come on strong if I don't eat the ground flax seeds. Supposedly the ground flax seeds trap the estrogen in the bowels. I'm 63 and it's been 3 years since diagnosed ER/PR+ Her2-. Just started Anastrozole 6 weeks ago. I take it at night and no problems so far except I am having a terrible time sleeping. I only get 3-4 hours of sleep at night. Not sure if it's the Anastrozole or not. I am also gaining weight but not sure if it's the Anastrozole or Buspirone they put me on for anxiety.
