Hi Caroline,

Welcome to Cancer Chat. With regards to the crying I believe one of the side effects of tamoxifen is mood swings. I had hormone therapy (zoladex) for prostate cancer and mood swings are a side effect too.

I found that every now and then when I heard or read something sad or even something good, I would have tears forming and on the odd occasions, they would run down my face. As a man, I found this very embarassing and used to try and hide this from my wife by feingning a big yawn. Probably didnt fool her for you ladies are not easily fooled. 

I found I had not control over it and just last week I spoke to a lady who has the same problem but who didnt know mood swings were a side effect of tamixifen. With regard to tirdeness, you have had a massive life changing experiance so it's not surpriding you feel as you do. Hoping that this helps, Take care, best wishes for a full recovery, Brian.
