Thanks, @ArkadyRose - and congratulations!
Happy to say my nausea is tapering off a bit...I'm still sick first thing in the morning, but then fairly ok for the rest of the day until I start to feel woozy again at night (but no puking then, only mornings). Sympathies to those who are feeling down about it - I was completely miserable two weeks ago and actually worried about starting to feel properly depressed because of it. Fingers crossed it gets better for everyone soon.
I sense my midwife is very pro-home birth, but I think we're going to stick to hospital as I'm a worst-case-scenario worrier. That said, my last birth was extremely quick, so there's a bit of a question mark about getting there in time again...
