Alternatives to Zoladex and Tamoxifan? & Genetic Testing for Drug Metabolism

@Wonk, I was on Tamoxifen for four years  and felt like I was ina permanent brain fog, not fantastic as a teacher!! I also endwd up feeling extremely anxious and teary, my oncologist put me on lexapro, an antidepressant, which helped me feel bettwr but certainly didn't help brain fog. Four months ago, aftwr constant gynae problems my surgeon switched me to Arimidex. Although my hands are quite painful, and my hips and s hboulsers ache,  i can finally think again!! My head feels much clearer! Definitely worth a try!!
Best of luck xxx
