Anyone else have or having this problem?!

I'm 8 weeks pregnant and since about 4 weeks I've had extremely bad nausea and vomiting... It's to the point now that I'm throwing up every hour. I've landed in the ER twice this week because of dehydration. I'm also a labor/delivery nurse so I know the usual treatment etc. Nothing even meds has helped at all... Anyone else go through this? What did your docs do that helped? Thanks in advanced
