I just have LOCAH, and I sweat a lot.  Also, part of the reason I was finally diagnosed is because I was 22 and I’d been having hot flashes since I was a kid, only they’d gotten so I just had them all the time.  I never wore a winter coat even in northern Vermont, cause I just heated the air all around me.  Even in the winter I was often wearing shorts and sleeveless shirts.  Once they gave me medication I had to buy a coat! 

I do have to be very careful in the hot weather because I can get heat-related sickness very quickly.  I used to work in a non-air-conditioned environment, and if it got hotter than 90 outside I had to go home or I’d get violently ill.  Would be interested in hearing from anyone else specifically about the heat-related end of things.  On dex the hot flashes are FAR fewer, but still struggle a bit with them.  I started having them before I even started my period!
