I can't say what will be an OK dose for you but I was on 50 mcg for years ( recently increased a little) and started in late peri. Some women find that higher doses of oestrogen are needed to eliminate sweats when progestogens are taken continuously. I have almost always taken my prog on a cycle and 50 mcg dose worked within a few days - and definitely sweats had gone completely in a couple of weeks - so if you are on cyclical HRT and they haven't abated - maybe a higher dose is needed? However if it is not sticking properly then that could also be the explanation - rather than dose. There are only 3 types of prog to choose from as separates - Mirena coil, Provera, and utrogestan (which is progesterone itself).
