Hi there
I suffered with serve HG with both my boys and it was awful, but the end results were worth it.
I was on Cyclizine (sp) by inject 3 times a day and also steriods, but this just reduced the frequency of the sickness, not the nausea. I also needed vit b tablets from the doctor and iron injections. Spent most of my first preh in hospital, but by the second (15 month gap between my two) just ensured I kept as much fluid in as possible.
I also tried seabands, acupuncture (gave relief for an hour or two), reflexology and most other remedies.
I found salty food helped early in the pregnany, I also used to have ice pops, frozen yoghurt and ice cream. I even had MacDonlads, which I hate with a vengence normally.
Both my boys were born at 37 weeks in order to stop the sickness, but they were really good sizes (7'2 and 7,4 respectivly)
DH is on the list for the snip, as I can not go through it again.
