I think I've decided to reduce to 25
My grand plan of putting 37.5 on during the day and 25 at night, I decided wasn't a good idea because I'm still experiencing some of these symptoms at night like that. So I feel like I need to test out 25 properly by giving it a few days at that dose instead of going up and down, day and night. I also don't know if fluctuating like that would cause me more probs than help, in terms of side effects - plus how do I store the removed patch bit overnight to be stuck on again the next day!?

And it's not very practical because I had to take that bit off around 6pm to be sure it had worn off by bedtime - and removing and storing bits of patch at 6pm, wherever I might happen to find myself, just wasn't going to work....!!
But I did do a Medichecks test at 37.5 before I reduced, for future info.
I'm really worried about what happens if the palps continue even at 25

I mean, what if all this never stops? It's not bad enough for me to stop HRT now, I am able to sleep at 37.5 and less - and I'm even getting through to 7am which is great.
But things are not yet 'normal'. The throbbing is minimal but it is still there very slightly. The fluttery palps are still happening a bit, when I sleep. They are not there when I fall asleep, but if I wake up for some reason, even lightly, they are there although not in an intense way as used to happen when I was woken up. It's just not 'normal' to live like this, even though I can sleep. I guess I'll have to go back to my GP and get a cardiac monitor for 24hrs....
Anyway I am probably catastrophising now, because for now I just have to hope that 25 is okay...
