Thanks again Wrensong, for taking the time to respond.
I have not found myself being prog intolerant before, so that is probably not the case (unless meno has changed that too in my body, which wouldn't be a big surprise given how many other changes have happened during the past year

) When I still had regular periods (before HRT), I felt always the best during second half of the cycle and the days before period. During HRT, I've not had any issues with utro and it has been particularly helpful in making me fall asleep. I still fall asleep nicely, but as said, keep waking up then several times a night.
I'm taking 200mg daily which is a high dose, but my doctor wanted to test if that would help with the sleeplessness and anxiety (which it actually did, until a few days ago). I tried 100mg before but that seemed to just flow through me without much impact. Maybe I am not metabolising it very well, as I remember also one blood test showing quite low prog, while I was on 100mg daily dose.
Thanks for the many advices you share, especially the one to pay insomnia less attention is something I need to start practicing. That's my real weak point -having always been a good sleeper, its so weird for me to not sleep and I'm catastrophising it, I know.
