oh yes... choco, i sympathise entirely.. i'm only just on 11 months without a period now, but the hot flashes have been steadily worse this past year.. summer does not help! but i think i prefer the flashes in summer - i'm already dressed for it for starters, unlike winter where i am taking layers off, and then putting them back on constantly, and ar con does not get as confused - heat the room, no cool it down! my poor husband does not have to freeze...
yes.. like you described, i can go from comfortable in an air con'd room, to unbearably hot in a flash! (excuse that one, i couldn't resist it

) i think i probably have the whole range of flashes, from the slow buildup to the sudden heat.. i sweat like crazy.. i hate it so much, but unlike Floater (no offence float...

) i will not go for HRT... i was thinking of Promensil maybe, or Remifemin, but the doc i talked to thinks they have the same kind of risks as conventional HRT..
