Welcome Granna,
Like Chick, I'm new to this whole hot flashy thing but have not been enjoying it much! And after reading through this thread and finding out it could go on for 15 years doesn't make it any more appealing.
I'm going to write down everyone's suggestions and give some of them a try.
Right now I'm trying the progesterone cream but have only just gotten started with it so I don't know if it will help with anything yet.
