Oh, I'm sorry to hear you're having such a miserable time. Morning sickness can be hard to overcome, but some scents work well for some women. If you can find a smell that helps to calm your nausea and increase appetite, you'll be much more comfortable.
Have you tried slicing a lemon in half and sniffing it? That might work. Also, peppermint extract can be soothing for your tummy, as can ginger. Use real ginger root -- cut of a piece to sniff when you need it, or chop some up and steep it in hot water (you can drink it as tea or just inhale the vapours). Deep belly breathing used to helpme sometimes, too.
I know how awful it feels to be nauseated all the time, but it will go away eventually. But if you're not able to keep anything down at all for days on end, I'd see your doctor as soon as you can to make sure you're not getting dehydrated. I hope you feel a lot better soon.
