All the best Louie,
I now wish I hadn't wasted so much energy worrying about it but couldn't help myself! I completely agree that resisting research is hard but the funny thing is that I can't research how my reaction will turn out until I've actually gone through the experience. So I thought I'd round out the information that is out there for others who like me may be dreading the process. All the best with your journey and I hope your body adjusts to it as easily as mine seems to have done.
Another thing which has helped tremendously is changing brands. I don't want to be spruiking for drug companies but the change in hot flushes between brands was really surprsing for me http://pinkandapple.wordpress.com/2013/05/12/generic-genox-vs-tamoxifen-sandoz-brand/
