Allicat I understand what you are saying about not being able to say what you really want or need to at the time with the doctors. I am the same way and only think of questions later. It is so hard to take all this in at the time esp when they bring something up you hadn't thought of. It seems that you have thought about your decision for some time and have legitimate concerns for you. Maybe just take a bit more time to rethink things before actually stopping, but at the end of the day it is your body and you need to feel comfortable with what is happening.
Good luck with it all. I have just started Tamoxifen and am already having hot flushes so I know what that feels like.
