Kathleen, just to say I tracked down a second hand copy of the Miriam Stoppard book you mentioned and have just finished reading it. Although it is available in a newer edition I opted to buy the 2001 version as I was keen to see what she had written about HRT before the whole Women's Health Initiative study debacle. I found it a really comprehensive and useful read which I know I will go back to again and again. I was surprised to see her mention formication as a symptom - I started suffering with this in 2014 age 37 but have only recently learned it was hormone related - I wish one of my doctors had read Stoppard’s book and been able to advise me earlier.
Thanks again for the recommendation!
