Arimidex and medication

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.

Does anyone have ringing in their ears due to the arimidex? I have just over a year left to take this drug and I CAN'T WAIT to stop. ( I was a stage 0 (.9 cm tumor/0 lymph nodes)....treated with Chemo (adriamycyn, cytoxin and taxotere), then radiation and now arimidex. ) I was almost 41 when this started, I'm 45 now and want my life back. Don't get me wrong, I want to be cured, but sometimes the side effects are disheartening. This sure does sound whinny and I am sorry. I am happy to be cured, but so tired of all the side effects!!!!!!!!! UGH Thanks, dpr
