That NASTY word...CANCER!!!

In August of 2008 I was diagnosed with breast cancer. I had a lumpectomy, radiation, no chemo (thanks to the ONCO DX test) and then started on Tamoxifen in January of 2009.  Just curious if anyone is taking tamoxifen and if so how is your body handling it.  I made the choice to stop taking it a couple months ago at about 3 1/2 years into it.  I have gained a lot of weight, I hurt everywhere and other complications I won't bore you with :)  My symptoms didn't get too bad until about 3 years in.  Would love to hear any thoughts you would share with me....
