I used to joke that sweat was fat crying. That was when I was intending to sweat and went to considerable efforts to make it happen.
I tried, for a while, to apply the same rationale to the dreaded hot flushes... No. I can sweat my way through two sets of sheets a night and still get out of bed heavier than I got in. There really is no justice in this world.
I suggest taking every item of clothing you own out of the drawers/cupboards and draping it around the house so you will, at any moment, be close to a garment that will suit your internal temperature. Be warned, the thermostat can kick in and out in seconds so whatever you take off, or put on, will be wrong, wrong, wrong immediately.
If you are having hot flushes at work you will need to apply the same principle. Your colleagues can learn to work in an environment that resembles an op shop that has been ravaged by a bus load of half cut CWA ladies. Marg
