Thanks to you both for your replies. I'm on 1/10. The swimmy feeling has now gone, but am getting annoying little headaches, not always enough to take paracetamol, I'm at end of 1st week of the grey tabs, so hopefully this will subside.
I'm not peri, I had ovaries removed end of 2017 so plummeted straight into full on menopause! Just wish they'd removed my bloomin? womb but they said they wouldn't as nothing wrong with it!! Ha!
