This was twenty-five years ago when gluten intolerance was being diagnosed as The Sons of Anarchy Samcro shirt and dietary guidance simply caused a worsening of symptoms. So whilst narcolepsy may not be directly related to diet very similar symptoms can be as a result of food intolerances. I was in a state of total collapse, sleeping twenty hours a day unable to work and a three-day exclusion diet cured me after fifteen years of ever-escalating health problems.
