Arimidex and hair loss

I was diagnosed with breast cancer in 2003, age 53. I had excellent medical care at NW Cancer Specialists, Dr. D. G., Portland, Oregon. I endured Chemo (8 treatments) I had a lumpectomy and 36 radiation treatments. I also took Arimidex from 2004 - 2009. My doctor suggested exercise would lessen the side-effects and he was right. I followed everything my doctor told me to do, it was very difficult at times, but we are talking about my life and the quality of my days, his suggestions worked. I began a regime of walking, up to 3+ miles a day, water aerobics 3 times a week and I joined Curves. I also took vitamins: Costco multiple vitamin, vitamin E & C, Calcium + D(Viactive), Melatonin (natural sleep aid), probiotics, and fish oil. I also drank up to 6 glasses of water a day. I am now "cancer free" and not taking any RX.

I have been taking Arimidex since April of 2005. I have two more years before I can be taken off of the medication. I had breast cancer, diagnosed Oct. 2004. I had a lumpectomy following with chemo and radiation before I started taking Arimidex. I have severe hot flashes, can't sleep at night. I am up and down all night long. I can't remember things I am always having to make list and writing dates down and sometimes I get confused. I have joint pain, leg cramps and hair loss. My biggest problem is I can't sleep. I am always tired.
