Thanks for the link and your comment. I stopped anastrozole after one morning last week when I had trouble getting out of bed and walking. Joint aches are a known side effect but this was scary. The joint stiffness did largely go away in a day or two. I called the onco's office. Was told to stop the med until I see him in mid-March. I also am having trouble being constantly hungry. I was told it was weight-neutral but not so in my case.
Sorry if I'm repeating myself: I also have high anxiety, depression, and trouble sleeping. My body seems to take time to rid itself of the AI. Cognitive decline/memory loss is indeed hard to assess. I don't know whether what I have is normal aging or not. I will check out the link you provided. Thanks.
