This sounds very promising to be experiencing improvement already, I feel for you its awfully distressing when you dont know whats going on.
I read a book called Oestrogen Matters, a total eye opener! The menopause specialist was pretty upset at my journey but its not their fault I guess
we are glad at last there is more awareness but it all takes time to filter out there.
I have a new lady GP now at my practice, she is very knowledgable and if she doesnt know she finds out. Wish we had more of these!
Long may your situation improve. The dizzy spells may also be down to lack of estrogen, not sure if you are on any other hormones other than pessaries
