I have a similar diagnosis, and Exemestane every other day is the best dosage pattern I’ve found. I constantly question the wisdom of taking an AI! I’m 71 1/2, and husband has major medical issues, so I need to be there for him in my “best self” if possible. I continue to take it, b/c recently when I played around with NOT taking it for an extra day or two, I felt worse. I’ve been doing this regime for 9 months…after refusing another pill of Letrozole, which caused bone pain in my legs. My only side effects now are some memory issues and occasional hot flashes. This is a hard one to know, factually, what to do!
