My daughter also suffers migraine but very rarely - about once a year. Her's is preceded by a loss of vision - the first time it happened we were on holiday in Devon and I freaked. She never had the dreams/restless nights that you describe. With hindsight, it probably accounted for the acute stomach aches she used to have as a small child which were diagnosed as IBS at the time, but no diet seemed to help. Both my parents suffer from migraines: dad's are preceded by wavy sight lines and mum's by uncontrollable vomiting so I'm hoping as she gets older that her symptoms don't get any worse.
