I recently 1/26/26 starting taking 20mg Tamoxifen. I seem to have a little trouble focusing and initially thought it was the combined events of downsizing, moving across country, lumpectomy in November, 5 treatments of radiation, the holidays, and accounting projects.

Wondering if anyone is taking supplements like B12 or Magnesium? Or other tricks.

I’ve been taking Tamoxifen for over a year now- it took about 6 months for the moodiness and brain fog to improve. What helped- walking every day, get outside, yoga, getting quality sleep, infrared sauna with a cold shower after, eating nutritionally dense whole food and limited sugar, and seeking support/ counseling.

Regarding brain fog: I had it mildly with anastrozole. I switched to exemestane and it seemed to improve. It might be just a placebo effect, but I think it's worth trying a different aromatase inhibitor. Best wishes!
