Thanks Hurdity - I'm really grateful for you taking the time to reply!
I'm 51 and about 2.5 years post menopause (I was a bit early...)
I started in Feb 2015 on the lowest dose of Elleste Duet 1mg and it seemed to be enough to get rid of my symptoms, so it stayed at that level.
When I switched to Estradot I started again at the lowest level , presumably because 'lowest' had worked before?
I don't know how the levels translate between a tablet and a patch though is Elleste Duet 1mg tablet = Estradot 25micrograms ?
Yes - I started this regime after I finished the last pack of Elleste and I had a bleed which continued for the first week of the new regime. It was bit 'fresher' and heavier than usual, but nothing excessive.
I did consider using the Utro vaginally, but one of my menopausal symptons I was addressing was irritable bladder, so I'm loathe to go down this route as I've read it can exacerbate this.
Presumably I'd need to see a private specialist to get the kind of 'medical supervision' for the different regimes you're suggesting?
I've yet to find a local GP who knows anything about HRT

That is so interesting about the alcohol! The two worst mornings/worst headache pain I've had have been after I've had a couple of glasses of wine the night before.
