Good for her if it helps, the condition she has sounds awful, the poor thing, and being under the world's spotlight too and probably being forced to announce her pregnancy earlier than maybe they would have done, like with Prince George. Hopefully some back home comforts and TLC from her mum and family will help.
I think that some women suffer very badly from morning sickness.
A couple of years ago I went on a brand of the Pill that I hadn't had before. I was feeling sick and puking up for about half a day. Doctor (male) says to stick it out as it was like morning sickness and it should settle. It was fekkin awful.
I don't like Kate or her man but she has my sympathy on this one.
I think she has hyperemesis gravidarum which is a very nasty form of morning sickness and can cause complications during pregnancy so she's better off staying at home away from the limelight.
when i worked as a macmillan nurse, sickness and nausea was the worst symptom for most people - pain can be dealt with but sickness and nausea prevent people from carrying out their normal lives, and actually had a much bigger impact. When you are Pregnant, you can't really take much for it either. I know when im ill, i just want to be looked after by my mum :)
