Hi Kinddogstail.
My GP wasn't really aware of the HRT I wanted, but, she listens, looked it up and was able to prescribe it.
My chemist hadn't ever had it in before and I had to show that it had been liscenced for use, (I printed off the medical council licence for them) so they could dispense it.
It was a bit of a palaver, but being on the menopause forum here and getting some really great advice from Polly amongst others actually I kept at it and got what I wanted. I'm delighted as its bio identical, and is exactly what my body would be making if I hadn't had my menopause early.
I'm using oestrogel, a bio identical oestrogen trans dermal gel that comes in a pump container, and utrogenesan, a natural progesterone made from yams I think, that is in a little oil based capsule. I rub two pumps of the oestrogel a day into my upper arms and I take one capsule of utrogenesan for 14/28 days, to mimic a menstrual cycle, but at a lower dose than I had when fertile. HTH.
I am surprised at how polarised the debate is because new evidence shows that over all, HRT is of benefit and can save women's bones, hearts, and relationships.
I guess we have anti vaccine loons on MN who shout from their soap boxes too. Maybe I should just accecpt there are some people who have plenty of opinions and like to give them an airing, ignoring the facts and evidence.
I'm not engaging with the debate, just in case anyone feels like having a go, and cutting and pasting my posts with bold highlights.
I'm just giving my experience to those who it might help.
It took me a while to find my path I want through the menopause, and I'm very happy with my decision to go on bio identical HRT, based on research and evidence, and supported by my GP who I respect as a fellow scientist and a person of professional integrity.
Maybe posting about my path will help someone to navigate their own menopause without the crippling tiredness, forgetfulness, night sweating, hot flashes, insomnia and bone aches I had. Oh, and grumpiness, let's not forget that 
Peace and love!
