Sorry, I'm very late to this message, but really felt I needed to write. Had HG with both of my girls. With the first, I stopped working and spent 4 months on the sofa - the usual story, nothing stayed down including water. It was grisly, especially since I was never officially diagnosed - and if people don't know someone who's had HG, they are just so awful.
I keep reading it's hereditary, but neither my mother nor grandmother suffered. Even my mother would say, you're not ill you're pregnant (And yes, i did want to punch her, if I'd had the strength).
When I fell pregnant with dd2, we moved in with my in-laws as soon as the sickness started. We'd been in Oxford before, and none of the GPs I saw did anything. Well, in rural herefordshire, I was really lucky and happened upon this super chap who did acupuncture, in my wrists. I can't recommend it enough. Yes, I felt just as awful, but the sickness went from every few minutes to maybe 2 x a day. This meant I could get by and vaguely look after dd1, who thankfully doesn't seem to scared by the experience.
I took the anti-emetics for 1 day, and the acupuncture gave me the same effect as those, if that helps.
I'm writing this because I really hope it helps someone else. Also, all the research shows that HG pregnancies never miscarry, and my dds are beautiful and very healthy!
I would love a third.....
