Hi, i am posting this for my mum diagnosed with breast cancer in January, she started taking tamoxifen 3 weeks ago and she has suffered terrible nausea, her GP advised her to come off the tablet a week ago, but that hasnt helped.  She is also experiencing tingles in her feet, but its more the nausea, we had hoped after a week of not taking it the nausea would have lifted.  Has anyone any similar experiences that they could share. Shes really worried now, its not the tablet at all and could be somethign else. 

She had a lumpectomy in February, but luckily no radiation treatment, she is 76 years old.
