Hi Kate,
I had to go back for a wider clear margin too; then had chemo & radiation. I started on tamoxifen but switched to zoladex + arimidex because the tamoxifen was making me feel nauseous. I was also on effexor for about 6 months. I was diagnosed in Jan 2009. I have put together some resources on my website www.hatiheri.com, including pics. Feel free to ask any questions about anything :-) As I am sure the oncologist has told you, we are all different, but it's definitely nice to have a chat/sounding board from time to time.
I hope it goes as smoothly as possible for you.
Tish
