Dear Momandrpho48
I was having the same issue on Anastrozole. It was called Brain Fog on the list of possible side effects.
Mentally I was just not me. I cried when alone and felt like I was saying ‘who is this person?”

In my research as to why I was experiencing such joint and muscle pain in my knee, I read how blocking estrogen for the sake of
breast cancer made me think of rephrasing the saying - damned if you don’t (take Anastrozole) - damned if you do. I learned that your brain and jounts/muscles are 2 vital parts of our bodies that estrogen plays a very important part and was being denied . While I didn’t go on my current hiatus because of brain fog, it has become one of the changes that I am most aware of and grateful for. As with the incremental recuperation from muscle/joint pain , the brain fog recovery isn’t instant but is very evident.

Just wanted to share what seems to be our similar experiences with Anastrozole and hope it helps you.
I have found it a problem that in order to alleviate a side effect of Anestrozole, we are prescribed or made aware of another drug to include in addition.

You seem very aware of yourself. Stay strong and remember you reached out here when you rightfully questioned what was going on. You can get comfort from this group but you more importantly can be made aware.
I hope you will stay tuned! ❤️

All the very best!
