After reading this I would have thought I wrote it, my issue us identical to yours, ughhhh, did you find anything to help you? My Dr. says "some people are just warmer than others and you have to live with it" when your dr says that it is so discouraging.
You all need to try Ditropan (aka Oxybutynin) tablets (Google it). I was always sweating from face, even just walking down the road in winter. These pills have dried the sweat up by about 80%. Small side effects like dry mouth, and slow to pee are present, but easily coped with, especially considering my life has been radically improved for the better.
Marijuana DEFINITELY helps and will keep me dry for about an hour. I wake up soaked, spend the day dripping with sweat constantly, and have to take precautions before handling any electronics or paperwork. I've literally damaged gear due to excessive sweating. I'm always uncomfortable, and due to my living situation I am at the mercy of others regarding the A/C thermostat, which is always set to a torturous 78 degrees. I live in the sub-tropics and would kill for one night of cool sleep.
My way of coping with this insanely embarrassing feature we are stuck with: I carry deodorant EVERYWHERE, and only wear black or a material that does not show wetness to work/social events. I'm about to try a bunch of suggestions from all of you though, maybe I can wear colors again!
Good luck to all of you
