Anastrozole
"I have atypical ductal hyperplasia.  Initially put on Tamoxofen, stopped secondary to multiple side effects to include osteoporosis and poor quality of life. Took 9 month drug free vacation before agreeing to taking Arimidex anastrozole. Hot flashes and insomnia have been dependent on what time of the day I take the medicine; worse if taken late afternoon/evening. Have had a return of joint/arthritic pain in hips/low back, shoulders and hands. Have fatigue, no libido and have gained 15 pounds despite being active and eating healthy. Short-term memory is poor and word recall is frustrating.  I know many do well on this medicine but not sure if I will stay on it."
