Hi Optimist
A lot of doctors start with elleste duet - it does the job well (provides oestrogen and norithisterone is very effective at protecting endometrium)suits a lot of people and it is cheap, so it is encouraged

(It is similar to when they start people on COC these days and give them microgynon).
If it does not fit you, then you need to change something. It is customary to change one thing at a time, so that you know what is working and what is not. If you change lots of things together, then you will never know for sure what is working

So what you do is change the progestogen, if you are having progestogen problems, let it settle for 3 months, then change the oestrogen/increase the oestrogen when you have oestrogen problems or not enough (or vice versa) until you get it right.

If you look above at Treatments/hrt preparations/ for perimenopause, you will see that elleste duet 1/10 is estrodiol and norithisterone and low dose, whereas prempak is conjugated estrogens, medium dose and norgestrel. So that is three changes all at once

So yes - go back to the GP and ask for Femoston 1/10.
If this is ok and the symptoms go away then come back again, then you may need to try a higher dose.
Hope it goes well with the doctor. Someone needs to write a blog on 'How to go back to your doctor and ask for the right thing, if you think s/he has got it wrong'
