I very much agree with what Hissy has said. Have you asked your vet if you can use (as is done with many kitties who vomit due to having kidney failure) pepcid ac (not the complete, the ac) - Patrick is on 1/4 of a tab once a day and it helps him a great deal. I would not do so without your vets approval, but it's worth asking them, just to provide a bit of relief until you find out what is wrong. Here is a page that discusses vomitting and nausea (with cool links to medical sites with information on this) Info on vomiting and nausea
and here is a page with treatment options (includes the pepcid ac and slippery elm bark, plus a link to how to make slippery elm bark into a liquid for giving orally) Treatments for nausea and vomitting
Even though this is a site oriented for care of cats with crf (chronic renal failure) the information is excellent and may be useable for you.
Best wishes for finding out what is happening with your kitty soon,
