Anyone have the Halo procedure done to get rid of the barretts? If so, after the procedure did the doctor put you on a bigger dosage of PPI's? A friend of mine had it done over a year ago and his doctor advised him to take nexium 40mg 3 times a day to keep the acid down so the area can heal. Has anyone heard about this? When you had your HAlO procedure done what took place afterwards? Was it painful? If it was painful how long did it take till the pain went away? Were you able to eat or drink? Please tell me about your experience.
