I"m 46 and have had 2 in the past 3 years - feels like a motorized fan of heat is buzzing towards me, then FLASHES (imagine that) from the center of my body and voomp up and out, then feel cold and clammy...the other new lovely is night sweats - cold and clammy...ick...there are tons of natural things, so far nothing has worked - switching to muslin sheets or 180 thread count helped, cotton breathable jammies, and keeping nutrition clean (ok, so I just ate a tollhouse cookie....ok, maybe I ate 4 of them - but they are considered clean at Christmas time - everyone knows that).....a fellow nurse friend of mine is in her late 60's and she used the progesterone cream you can get from vitamin world - the max strength one, and she claimed that helped her.....too much soy can stimulate estrogen and could be a cancer abetter, so I wouldn't overdo anything...wild yam is also dangerous in pill form.. but I'll take suggestions!
