Crispy, I think you misread the tone of that earlier post. It wasn't meant to be harsh, it was meant to be a bit jokey really. But anyway, we can all have a say and there is no need to try to find a definitive answer because often there isn't one with all this HRT stuff.
Spacey, the thing is... If you have tested your E and found that it has come back between 250 and 1400, you can be pretty sure that the most you are absorbing from HRT is getting you to 250. And that's including what your own body was making at that time. In other words - when we test and we get really high results, we have no idea if those are coming from HRT or from us. But if we test and the result is low (which 250 is) then we cannot be getting a stable and reasonably high amount from the HRT - or it wouldn't have been possible for levels to dip that low. Does that make sense?
During peri we are trying to stabilise the fluctuations and often higher levels work better for that because when we cut out, it doesn't go to nothing (or 250) it goes to (say) 450 or whatever we get the HRT up to.
Which is all to say - especially since your night sweats have got worse - that you likely need more estrogen, not less.
