how can I overcome the nasaua and constant tinny taste in my mouth that I get while taking tamoxefin? I m on year 3 of taking it and I also have to take toprol XL for an enlarged heart that i had 30 years ago. Also, I had thyroid cancer 6 years ago, so I have to take synthroid too-300mmg daily. This was after i had Hodgekins disease in 1978 and 1981-radiation the first time and chemo the 2nd (vincristine, pristine, prednizone, nitrogen mustard...) The chemo eventually caused me tohave both ankles operated on and both knees replaced.
