Tamoxifen
"This drug is nonsense. They tell you the side-effects are minimal and easy to deal with - as long as you tell your doctor.  Well, it's been three years and the only thing the oncologist has recommended for me is psychotherapy (apparently because I complain too much).  Now I have to have a hysterectomy because I have "unusual" growths in my uterus. I look like I'm seven months pregnant and am now having to shop in the maternity department. I'm not pregnant, BTW.  Evert joint in my body aches and I sweat at least a gallon a day. I've had to buy a new mattress and pillows since I ruined them (with night sweats). To top it off, my oncologist doesn't think any of this is caused by Tamoxifen. I am tearing out the little bit of hair I have left."
