Tamoxifen dosage? All for one and one for all!

Hi Lisa. My Oncologist told me dosage studies had never been done so they don't know. It wasn't in drug company's interest to conduct them. Side effects on these bloody drugs were a lot worse for me including mental illness.  I only took 2 a week which seemed to be fine for me then my Onco put me up to 3 a week. After a while i had to stop. Next time you see you Onco ask about the dosage studies?  Would be intetested in the answer. These doctors need to understand one size doesn't fit all.
