Hot flashes really are worse in hot weather, since mine have also flared up since it started getting warm.
Speaking of fans, here's what I do: I moved the bed to about two feet away from a wall. I placed a small floor fan on the other side of the bed, two feet away, and aimed it directly at the wall. The air hits the wall and then swirls around the bed, but there are no direct drafts. I also have a ceiling fan on medium speed. This whole system seems to keep the air moving nicely.
Good advice to "ride the wave," iluvtolaff. I have tried that and you are right. It's much less exhausing to just lie there quietly, because after the night sweats I get chilled. The only thing I do with a night sweat is I must throw the covers off or I roast, but I try to just throw them off quietly without thrashing, and after a few minutes, the good old chills start, and back on go the covers.
I know; it's all a real circus, complete with a merry-go-round and rollercoasters every night!
