Was a choanal swab for cultures and blood work done? Because giving something for the nausea will stop the vomiting but it will not cure whatever caused it and, with birds, vomiting is always a symptom of something not quite right. If it was something she ate, then one would think that vomiting would take care of it but I've never had, heard or read of a bird that would vomit because of this reason unless it's extremely high protein in a very young bird for some time. Birds swallow even pieces of metal and get metal poisoning from them without bringing them up so it's not like humans who can eat something, say, too fatty, and throw up. Humans swallow and the food goes directly into the stomach while birds swallow and the food goes into the crop, then to the proventriculus and, finally, to the ventriculus. When they vomit, it's from the proventriculus while they regurgitate from the crop.
Now, as far as I know, there are no 'normal' reasons for a bird to vomit (except in the case of the super high protein). It can be something as easy to cure as a bacterial infection or sour crop but it can also be something as serious as PDD, passing through megabacteria (which is not really bacteria, this is the 'old' name), Pacheco, polyoma and even a blockage (is Monty pooping normally?).
