Thanks for that, yeh it's quite scary! I don't know of anyone in my country (NZ) that is having such a bad time through menopause, so lucky to find this site! I think I need to have another go at HRT but not sure where to start as I had a bad reaction last couple of times I tried them. I think quantities and type of HRT needed are so different for everyone, but here, they seem to treat everyone the same! What is a silent migraine? I certainly have headaches a lot.
