@Nannatash I was put on Vitamin D immediately finishing Chemo and still take it everyday and I am 16 months post, I take it with Vitamin C for absorption but the biggest one is Magnesium as that services over 300 enzymes in the body at a cell level. Check with your Oncologist in a few weeks, but all of those things are safe and will help alot. Tough as through chemo its depleting everything so nothing sticks. I was put on Arimidex 6 weeks later as you were Tamoxifen...I also was already having hot flushes so its menopause not the medication. You'll do great! x Melinda
