Tamoxifen

Hi I have been using Dr. Schulzes products for a while now and really like them. I was diagnosed with very aggressive breast cancer in new year of 2013. Yeah, Happy new year to me. Anyway since then I have gone thru chemo, radiation, double mastectomy. Now my oncologist wants to put me on tamoxifen for 5 years! When I was reading the side effects I am terrified to even start. Any advice or experience on using alternative natural product to protect me so I could continue my life without worrying that the cancer will return if I don't take the drug. Thanks,

Anita
