Hi Kerin,
I took a break for six weeks off tamoxifen to see if the joint pain, night sweats, etc I was suffering from was relived. As suggested by my doctor. I was told that it can 'reset' the drug. I had no withdrawal effects, I did then decide to go off tamoxifen totally. I had been on it for two and a half years. Yes, my doctor does know. It is a personal choice of mine, but I hated the drug. I am now going through menopause again! Naturally
It won't hurt you to go off it for a short time.
all the best,
Liz
