Please don't be fearful of side effects.
At present your body is in fatigue mode after all the treatment to date, not unusual! Fatigue was a major factor for me and it is only as time has passed that my body has adjusted and I am in a better place mentally and physically along with making a few changes along the way.
It is not always wise to read the side effects prior to taking as that is where the fear builds and as mentioned above those with side effects make noise as they look for others with similar and look for support on how to combat them.
You maybe one of those that has minimal and maybe none and just sail through.
The options are there with consultation with your Oncologist to change medications if the side effects are a problem.
Have you seen the BCNA booklet on Hormone Therapy?
There are links within this link that hopefully can give you a better understanding of this next phase of treatment
