Oh I have been getting this recently. Drop off to sleep okay but then wake up with a real jolt, convinced a huge lorry has just thundered past our house (we live on a busy road) or that my mobile alarm has gone off. Neither has actually happened my husband tells me

It's horrible, and if I'm in the second half of my cycle I have a devil of a job dropping back off to sleep again. And of course the more it happens, the more you start to believe that you WON'T drop back off to sleep, and so you don't

I am 44 and am waiting for a prescription from my consultant for HRT. I am hoping and praying it can somehow magically turn me back into ME again.
