I, too, noticed the very thin mention of HRT in that otherwise utterly depressing (14 years' of hot flashes!!!! Aaarrghhh) article. I lived in the U.S. for 15 years, now back home in NZ and recently went back on HRT because primarily of miserable sleep deprivation brought on by endless, repeating night sweats.
The way HRT was given such short shrift in the article annoyed me, as did how -- to my mind -- hot flashes/sweats were treated somewhat lightly. I suppose not everyone is as crippled by them as others and yet somehow it all still seems a bit ha ha at times...one woman talked about not being able to wear silk, anymore. I don't mean to belittle her symptoms, since she also said she needed a fan on her desk at work, but if not being able to wear silk anymore was anywhere close to an issue for me, then I'd be happy as a clam, really! But getting no sleep night after night and feeling utterly depressed and barely functional as a result... That's my experience of the sweats.
