The sharing of info like this is so helpful @kmakm. I was on Tamoxifen for the first 2 years and then swapped to Femara after having my ovaries removed. I had almost no noticeable side effects on Tamoxifen (except for mood swings my husband will tell you ;) ).
But Femara was a bit tough to begin with. I have now been on it for 21/2 years. Like you my oncologist has said 10 years all up is the likely path for current recommendations. That means 51/2 more to go. :#
Experimenting with different supplements is a very methodical and thorough way to go. While some things appear to work for others it is a bit of trial and error as to what cocktail works best for you. My osteopath told me that in her experience most people have a bit of an inflammatory response which seems to settle in time. I found it seemed to hit me about 1 month into taking Femara.
I now take Curcumin, high strength fish oil and magnesium. That seems the best for my aches and pain type symptoms. My 2 other side effects have been bone loss and vaginal atrophy. The weightlifting is curbing and reversing the bone loss and I am managing the other with the help of my gynaecologist.
I do feel very high maintenance these days! :D
I hope that you work out what works best for you and can manage a decent quality of life on it. That is what we all want. Take care. xxx
