Aww ok I see. Makes sense to switch then. How long were you on tamoxifen so far? Did you get any side effects? I started with 20 mg the standard dose but got some pretty annoying cramps like a week and a half into treatment. My oncologist told me to cut the pill in half and do 10mg everyday instead. So far I did not have as much cramping so I hope that dose will work for me moving forward.
