How far gone are you? I'm 12 weeks and in and out of hospital for something called hyperemesis gravidarum. This is basically extreme sickness which lasts all day everyday and results in rapid weight-loss. I go days without keeping down even water which is why I need to go to hospital, to go on a drip and get re-hydrated. The differences between this and 'normal' morning sickness are, with this you lose a lot of weight, with morning sickness you don't, this interfers largely with day to day life, morning sickness doesn't, with this you need someone looking after you. Try and google it to find out more, and talk to your doctor. If you carry on like this for days withouteven keeping down water you will need to give a urine sample where they check to see if you're de-hydrated. It's good that you feel hungry though, most of the time the tought of eating alone makes me sick! I think you should consider a few things, how long has it been going on, can you keep down fluids? I really do feel for you because I know what you're going through, I have lost a stone now through being sick, I can't get out of bed. But remember, the more sick you are, it tends to mean the healthier your baby is!

If you are able to keep down fluids, try chicken broth or different kind of soups, that way you are keeping something down and getting at least some vitamins and minerals. Try it out.
Also some things that might stay down are crackers. Also try ginger ale, or ginger tea, the ginger is good for nausea and might help you be able to eat something.
And yes feeling hungry is a good thing. You just need to find something that your able to keep down.

Lemons and lemonade help with nausea. I also reccommend anything with ginger. Ginger snaps, ginger chews, ginger tea, ginger ale with real ginger. Ginger ale with real ginger is difficult to find though. Make sure to read the labels.

What helps me is mint! I chew a piece of mint gum, or drink some mint tea, and it helps alot. I think i heard Vit B6 helps too. You may need to try differant prenatals. some women have to take flintstones vitamines.

You might try eating Altoids. They have really helped me b/c they have real peppermint oil in it.
