Sometimes it’s best not to read the list of side effects when you begin a drug - it just terrifies you and most of them you will probably never get. I started tamoxifen 3 weeks ago and other than being hungrier I don’t feel any different yet. No doubt in time I will but I was already having awful hot flushes and headaches, night sweats, muscle aches etc from the chemo and so it has all just blended in 😊 I don’t know what is causing what anymore. Then there is the afternoon energy collapse where I don’t know how I will get through the evening meal followed by being wide awake for hours during the night. It’s all FUN! I can’t blame any of that on the tamoxifen - I have just had a big year and now 15 radiation treatments in I can add that too.
My mother has just finished her 10 years on letrozole and while her bone density has suffered she has always said it didn’t bother her at all as far as side effects go.
