Geri,
You can look here for info on Tamoxifen followed by Femara:

BTW, I recall reading that the brain is one of the largest sources of aromatase production in the body (stands to reason, there is a lot of fatty tissue). This study Lani posted may show that Femara crossed the BBB and inhibits aromatase in the brain - wouldn't that be great?
Hopeful
