It must be the Anestrozole. I've been using the wrong words for things. Yesterday I changed my sister's dog's pee pad. My husband noticed I put the plastic facing up and little Pom Pom went on it. I took it for 3 months after a lumpectomy and went off for 7 weeks. I had DMX and the surgeon had me stop. I waited a while too long to restart according to the Dr. I've only been back on it a week. Right away I felt like I am mixing up words.
