I'm so sorry you're going through this - I had "morning" sickness all nine months of both of my pregnancies. Truly a wretched experience, lost lots of weight each time.
That said, there are things you can do and everyone here has offered great suggestions. I recommend that you be prepared to try ALL of them since you never know what will work for you. And you may find, as I did, that no one thing will work repeatedly but you might get a couple days out of one solution only to have it stop working.
So, ginger chews (available at Whole Foods), lemon candies, sea bands, some kind of liquid treatment for reflux (Mylanta and the like), coke classic (some people respond well to the sugars), and so on. Pregnancy websites have lots of solutions along these lines. Distraction, as another poster pointed out, is definitely a help. The more time you have available to dwell on not feeling well the worse it is!
Also, talk to your doc. Depending upon your case (i.e., if you're losing a lot of weight) you might be a candidate for a drug like Zofran to help control the nausea. It's VERY expensive ($30/pill)and you may have to get insurance approval first but it works well. Another solution to discuss with your doc is the Sominex/Vitamin D combo - do NOT be afraid of hysteria you read about on the Internet about this. Your doc can give you the straight story.
Finally, you may be one of those lucky women who finds that they begin to feel much better after just a couple weeks of the yucks or can manage things with just a couple crackers and a ginger ale. So don't get too down...and, GOOD LUCK with your pregnancy...Congrats!
