Excessive vomiting symptoms and conditions

My little boy who is now 4 has been off the Reglan for two years. I really thought my husband and I were doing the right thing by putting him on the Reglan at 8 months because he was vomitting blood. The gastric doctor said he had to be on it plus prevacid .Well I WISH WE HAD KNOWN THE SIDE EFFECTS. Now my son is in the process of going to a Neurologist next week because they think he might have Tardive Dyskinesia . He has the symptoms of it on and off for a year now and the doctors have said it is from stress not possible because all of the stress therapist we have taken him to say he is not stressed. I would like to say one thing do not put your child on this drug because it could be the biggest mistake of your life . This is a disease that can not be curred.

Dark urine, severe left upper quadrant pain, tachycardia, patient look very sick and worry. Black stool, nausea, excessive vomiting.
