Thanks CBA. Yes I am already on "long cycle" progesterone therapy and am due for another round but scared stiff given my last trial was horrendous. I had hoped to be better "balanced" on estrogen - currently I've reverted to oral (estrofem) as I've a feeling I do better on a daily dose rather than the trickle dose of a patch. But I still seem to have some really challenging days/weeks a month, that I associate with ovulation/cycling. Even though I am on Lucrin to suppress my cycle (and it does have a dampening effect - because I've tried without it), I still experience some breakthrough symptoms - anxiety, low mood, headache, nausea, poor cognitive function. I've almost accepted this is the best there is until I am fully menopausal because I have tried pretty much every form of estrogen and progesterone (apart from the Mirena), and obviously not tibolone.
