I had a Hystorectomy(sp?) in 1989 and was on hormones for about one year but decided they were't for me. I have been fine until about 1 year ago (turned 54) I started having night sweats once in awhile, now as of late it has been every night, wakes me from a deep sleep and sometimes lasts for an hour before I get comfortable again.What can be causing this? Anyone else have this?
