I have just bought one of these magnets today to help reduce the symptoms of the menopause and side effects of tamoxifen. (Ie: hot flushes, night sweats etc). Has anybody else tried this device? I understand it is safe to use with Herceptin and tamoxifen, but I am currently taking some heart drugs too, (Ramipril and Bisoprolol), as the Herceptin is weakening my heart. I am cautious as I cannot find any reference to heart meds and this product. Can anybody help? Thanks,
