@cfetoday there is quite a difference between 14% and 8%. Respectfully, are you sure you don't want to try anastrazole or another aromatase inhibitor? Many of us had minor side effects. I found that if I walked more than 30 minutes, any joint pain eased.

Many of us have found that the manufacturer makes a difference. I tried anastrazole generic, then letrozole generic thinking the problem was anastrazole, but it was the fillers. I ended up doing brand name letrozole (Femara) and toward the end did find a generic that was fine.

I was 63-68 during treatment. I am 9 years out from a grade 3 invasive mixed cancer.
