I'm going thru menopause and i'm getting hot flushes and night sweats or so suffering insomnia cause of night sweats what can i take to stop this?

Depends on what you: treat exactly. There are all kinds of herbal supplements that may help. I have had success treating with black cohosh and ginko. You may have to try a few before you get it correct. There are medical hormone replacements but try the other stuff first.

Hot flushes: Different options are available treatments of hot flushes. Depending on other medical problems treatment options can be evening promise oil capsules ( not proven to be very effective) , tablets like SSRI , hormones etc. your GP can guide you and start appropriate treatment .
