I’m 60 and started anastrozole in June. I had many/most side effects that you hear- constant headache, bad hand joints, moody, fatigue to name a few. My doctor and I agreed for me to stop taking it for 2-3weeks to see if side effects went away. I did feel back to myself after a couple weeks. I have now started Exemestane. On week 2 and doing well. I have been walking and exercising more, eating better and rarely have alcohol. I’ll hoping this will help.
