I am experiencing the same. I had a double mastectomy and am now taking arimidex. Hot flashes are a b. They seem to be the worse at night. I sleep under a ceiling fan at the highest level. (my poor husband). I do take sleep aids. I am taking Lunesta. I like you do not like taking it but If I didn't I would not get any sleep and neither would my husband and there is no better feeling than getting a good night's sleep. I also have been told that if I take my calcium pill before bed time it would relax me. It does seem too. KY gel has helped me with the dryness. Good Luck
