well, I haven't been on hrt all that long, and it is winter here. But I have noticed I sweat much less than previously and I can wear warmer clothes now without overheating.
A few days after starting hrt, I did get some sweating and hot flashes, but I understand that was probably the stage when my hormones were switching over, or both were very low... It only lasted not even a week or so.
O, and the no stinky thing, I LOVE it!!!
by the way, not everyone responds the same to hrt, so just give it some time and discuss such issues with your endo when you see him, it might just be incorrect hormone levels.
