Arimidex
"I only took Arimidex for 1 month, after having a mastectomy. During that month I experienced severe joint pain, nausea, headaches, shortness of breath, and finally, a severe asthma attack which convinced me that I needed to stop this drug.  Almost immediately, all side effects disappeared.  Now, eight months after stopping Arimidex, and taking nothing else, I have quite severe Rheumatoid arthritis.  I was previously fit and active.  I am 70 years old. I would rather take my chances with the cancer returning than take this drug again."
