My 7 year old son has often headaches that lead to vomiting 9 out of
10 ten times he has a headache sleeping it off usually helps. his doc has prescribed a antihistamine called ic cyproheptadine to help he takes it twice a day liquid form. It does help lesson the headaches and vomitting but still they occur roughly every few weeks. He doesent eat or drink any recommended foods or drinks the doc said to stay away from soda sweets lunch meat chocolate etc which he never had beforeanyway. curious if he might have a food allergy, or gall bladder maybe even an appendix issue?
