Mary G, I too have been thinking that the current guidelines are simply over prescribing progesterone for many women!
I have tailored my own dosage through trial and error, but I could tell right from the start that the prescribed dosage was very much too high for my body.
From reading this forum it is clear that many women aren't able to do this - because they don't feel confident in doing so, or because they can't access scans to check what is right for them. And that is such a dreadful shame. I am sure many women are having to put up with a poorer quality of life as a result.
The NHS sadly is significantly underfunded and as things stand this is only going to get worse. Unless we, the voters, accept that we need to pay for good services, then I doubt that things like tailored HRT regimes will ever be anything more than a vain wish.
