Banger,
i'm 38 years old and have been through menopause because radiation but just wanted to say that hot flashes can be extremely troublesome. There is a lot of information out there but it's just like anything else - different things work for different people. My flashes don't so much soak my clothing anymore (it just feels like my head is so hot it is going to blow off--lol) and sleep with the airconditioning on 64 degrees f, the ceiling fan on, as well as another fan blowing on me. I flip covers on and off all night. Some of the things i've been told and read to help combat the hot flashes and other symptoms of menopause are but not limited to:
reduce or eliminate caffeine, take vitamin e, there are many herbs that suposedly help, soy, hormone replace therapy (i caution this one without lots of research on the patients part), diet changes
there are so many things that may or may not help that I can't possibly list them all here. I know that I sleep with my hair up and that actually helps some. I've been having the flashes for over a year now and hope they stop one day!!
My best suggestion would be for you or your mom to do a google search of menopause or menopause remedies and start researching and trying things. Good luck!!!
