Pre-menopausal starting Fareston???

ArmyWife322007

I'm almost 38 years old, always been in good health, never been pregnant.  I was, however, on a birth control pill for 13 years (I started when I was 24) and was told to stop it last November after being diagnosed with Invasive Ductal Carcinoma.

My 1.3cm tumor was in the left breast.  My lumpectomy was performed on 12/4/08 and was Stage 1, node-negative, Grade 2, estrogen-receptor-positive. 

My ONCOTYPE test scored at 18 and my oncologist therefore determined I didn't need chemo.  I just completed 6.5 weeks of radiation 2 weeks ago.  My oncologist wanted me to go on Tomaxifen now but I'd already been on it 6 years ago for a completely unrelated medical condition and had miserable side effects and stopped it after a few weeks.  As an alternative, he wants me to go on Fareston.  Has anyone else pre-menopausal taken it?  From what I've read so far, it's prescribed for post-menopausal women with metastatic BC and has basically the same side effects.
