<s>[INST] My 10 yr old daughter wakes up about once a month vomiting everywhere! Its always in the middle of the night and she will have vomit in her bed, floor,etc.! Sometimes it will only happen once, but it usually happens a few times before morning with usually no other symptoms and she wakes up fine! She was a horrible bed wetter until a yr. or so ago, and then this began! Shes also a sleep-walker, and before she was sick tonight, i heard her talking in her sleep! Weve tried to pinpoint a certain food that could be causing this but what she ate tonight, i know shes not allergic to. One last thing, she complains often of headaches, normally in the afternoons, but i thought it was from the hr long bus ride home from school! [/INST] HiWelcome to the HCMThe symptoms of your daughter can be due to certain reasons like seizure disorder, psychological stress or just a peptic ulcer disease. I would recommend you to take following measure to help her out:1. Sleep EEG to rule out seizure disorder.2. Visit a psychotherapist for proper psychological evaluation3. Start her on Omeprazole ( antacid drug) at dinner. Ensure plenty of fluids orally and avoid any spicy and oily food.You may upload her report for my reference. Hopefully this will be of help.Take care </s>
