Last resort nausea remedies?!

I don't know what to do. I can't go to work because the nausea is so bad. I've only thrown up twice luckily, but I feel like I'm literally going to puke any second all day long. (I'm a nurse so work is a bit more difficult while nauseous) I can't sleep and when I finally do sleep it's the only thing that helps. I've tried everything it feels. I started on ginger ale and saltines and now I can't look at either. It's getting to the point where I've lost an appetite for almost every thing. I do take diclectin/diclegis, but it honestly does nothing for me anymore. I've tried jolly ranchers to suck on, popsicles, etc etc etc. I'm so grateful and blessed for this little baby growing inside, but I don't know how to manage the nausea anymore!
