Reflux: Rather than truly vomiting, you may be experiencing reflux or eructations from a hiatal hernia, incompetent lower esophageal sphincter or other esophageal motility disorder. Follow a bland, low fat diet, avoid large meals and don't go to bed with food in your stomach. If symptoms persist a gastroenterologist is best qualified to evaluate and advise you.
