Try not to make any assumptions about tamoxifen. Most of us worry about it and then find it not near as bad as we thought. I have a few hot flushes but there are things you can do to help this. Lots of ladies (me too) find that magnesium tablets can help with side effects. I found they helped with energy/emotions and muscle cramps. Some people find they help with reducing the hot flushes too.
I have found that getting some exercise each day seems to help my body cope with the tamoxifen. I have been on it for almost 12 months now. Hope it goes ok for you too. Take care. Deanne xxx
