This is exactly what I'm getting at the moment, but for me it was worse at higher doses and better when I reduced. I'm now at 37.5 and it's still happening but not in as extreme a way. I wake throughout the night, feel that I'm throbbing a bit like this and can now go back to sleep (to wake another hour later and find the same thing).
I think it is associated with palpitations and high blood pressure. High blood pressure can cause palpitations apparently. And would also explain the throbbing and feeling that the bed is moving. But it's a mystery to me why estrogen is causing me to react like this seeing it is allegedly supposed to help blood pressure...

At 50, I felt like the bed itself was moving under me. At first I thought it was my husband scratching himself

so I sat up quickly, to see what he was doing before he could stop(!) - but he was fast asleep and that's when I realised it was coming from me.
When I went up to 75, I laid awake in bed all night with a fluttering in my chest (which tends to happen at the same time as this throbbing) and I even went to A&E the next day - but had a normal ECG.
If you look back at the thread about 'allergy to estrogen' there are many of us suffering from this kind of thing. But for me it seems to be caused by estrogen itself and the more I take, the worse my symptoms get....
