There has clearly been a comprehensive workup performed for the refractory vomiting. If 7 hospitals and 15 doctors cannot figure out the problem, it would be unlikely that I can come up with anything new.
Here is some information of cyclic vomiting syndrome. Unfortunately, no specific therapy has been proven to be effective for CVS in controlled trials.
Antimigraine medications have had some success. Agents that have been used empirically (with variable success) include sumatriptan, erythromycin, oral carnitine, propranolol, cyproheptadine, and tricyclic antidepressants.
Antidepressants have also been tried, including amitriptyline (median dose 50 mg daily), doxepin (median dose 50 mg daily), and nortriptyline (median dose 50 mg daily).
All these medications can be discussed with your personal physician.
Here is a support group for this frustrating disorder:

Followup with your personal physician is essential.
