Severe Nausea

Currently 6w4d and the nausea has only gotten worse as time goes on. Today, we contemplated going to the hospital because of a fever and chills on top of everything else. What has everyone done to ease nausea? I've already tried ginger ale, ginger snaps, preggie pops, crackers, and sleeping it off. I can't even function right now! It's been the couch all day for me with my poor hubby running around getting me drinks!
