My son is 15 years old and a healthy, active boy. He has recently began feeling naseaus in the morning and feeling light-headed after standing too long. If he eats breakfast he often vomits. This only happens in the morning. The rest of the day he feels fine. Usually symptoms occur if he wakes up early. When he sleeps in he is fine. Even when getting up early though, he is still getting at least 8 hours of sleep at night.
