Patients will be provide answers to one or more of the following: Rome III criteria, BARF pictorial scale, Nausea Severity scale, Children's Somatization Inventory, State-Trait Anxiety Inventory, Functional Disability Inventory, and the Nausea Interference Scale.

EGG is a non-invasive technique for recording gastric myoelectrical activity using cutaneous electrodes placed on the abdominal skin over the stomach.

HR- EGG utilizes an array of electrodes to estimate the direction and speed of gastric slow-waves using cutaneous electrodes placed on the abdominal skin over the stomach.

MGG measures spatiotemporal properties of magnetic fields from the gastric slow wave and allows characterization of the propagation of the gastric slow wave in addition to evaluation of its frequency and power distribution.

Electrocardiography is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin

Patients will be administered 4mg or 8 mg ondansetron dependent upon age in order to assess the effect of ondansetron on the symptoms of nausea and changes in slow wave dysrhythmias.

Patients will be prescribed a 5 day maintenance dose of cyproheptadine using dosing 4mg twice a day to examine the effects of pharmacological alteration of specific nausea pathways on gastric slow wave patterns in functional nausea patients
