Just because you are on 100 mcg patch which is theoretically a high dose - does not necessarily mean it is a high dose for you and docs should really understand this. The dosage levels ( low medium or high etc) are arrived at through a series of measurements on individual women which are enormously variable and the dose strength is an average of these. I can't remember if it is patches or gel but in my "go to" paper about absorption of hormones either patch or gel can result in a TEN-FOLD difference in systemic estradiol levels in the body. If you are a "non-absorber" or absorb poorly then 100 mcg is not high for you.
Also yes in some parts of the body, progesterone can interfere with the beneficial effects of oestrogen on the body - it doesn't reduce levels as such as far as I understand but can reduces its impact. Many of us remain with a cycle for that reason even well post-meno and even in our 60's!! Some (stellajane is one) increase oestrogen while taking the progesterone part of the cycle also because of this reason ( not sure if she still does - hopefully will read this!).
There is no way I would want to take any form of progesterone every day anyway as it has a sedating and dulling effect.
I calculated that the amount of absorption from the Mirena is very approx in the same ball park on average as from a Femseven patch - but of course the amount from Mirena is high to start with and declines over the years it is in place - but it depends how sensitive you are to synthetic prog . Have you ever taken the pill?
As for the ADs and lavender - that's appalling!! She wnats to get you hooked on happy pills like many of the nation...
She is out of order not asing the consultant for advice ( if NHS) and if she won't consider any modifcation to your regime despite your return of symptoms I would (in the nicest possible way!) demand a referral to a menopause clinic nearest to you ( there are none near me though).
Good luck and keep us posted
