There are many things you can do to help alleviate hot flashes. They are caused from hormone fluctuations. How long they last, how often they occur etc. is an individual thing--each woman is different.
I would suggest that you visit the rest of the site where you will find a wealth of information on this subject, as well as what you might expect in the future. I would start with the Recommendations page, which you can go to at http://www.dearest.com/recommend.htm or you can access it through the drop down menu at the top of any page on the site. I hope this helps.
