I started having blurry vision after we moved to Scottsdale and found out that my eyes were "too dry." The desert and chemo both are drying. Lubricating eyedrops solved that problem. My eye doctor also told me to take alginate oil -- skipping the middle fish. But the symptoms for these 5-10 year meds like estrogen suppressors seem endless and multifarious. I'm switching from Letrozole to something else because my neuropathy from chemo got markedly worse after a couple of days on that med.
