Hi rbaylis
I am sorry to hear about your history of breast cancer - I presume this is your mother or sister maybe? I think your risk of developing this depends on how many relatives have had the disease and at what age - coupled with genetic factors.
I really would not take Temazepam regularly though - from what I understand this is strongly addictive and once you start taking it regularly it is extremely difficult to come off it.
If you cannot take HRT and have been advised against it by your doctors, then there are other prescribed medications that may help with flushes and sweats and therefore enable you to sleep. They are listed in this section of the website:
http://www.menopausematters.co.uk/prescribed.phpIn addition there are other ways to help lessen the incidence of flushes - reducing weight to healthy BMI (if overweight), reducing caffeine, alcohol and spicy foods, increasing exercise, and trying to make changes to your lifestyle to reduce stress if possible. There are various products that may help eg specific duvets, sleepwear fabrics, cooling pillows and fans etc - I can't advise on these but maybe start another post in the alternatives section as I know these have been discussed before - there are also threads too but I couldn't remember where - so best to start a new one!
