Hi antoinette
I am so sorry to hear about the rough time you are having on tamoxifen. We often hear from women in a similar boat - you may like to read a previous blog post that has attracted a lot of comments from other women sharing their stories with tamoxifen.
If you haven't already seen it, we also have a booklet available called Sexual Wellbeing and Breast Cancer that addresses many of the issues you've raised, including hot flushes and sexual wellbeing.
It's probably also worth mentioning that if you do decide to take any additional supplements or herbal remedies, talk to your specialist (you may like to see another doctor if you don't think your current specialist will be helpful!) beforehand. Some herbs interact with tamoxifen and make it less effective unfortunately, so it's always a good idea to check with your doctor to make sure any complementary therapies are OK to take.
Wishing you all the best antoinette, and good luck!
