One thing my consultant used to say to me was ‘don’t feel guilty’. In his view very often the foods commonly viewed as triggers - and he was specifically talking about chocolate in my case - are not the real culprits. Rather, the ‘pro-dromal’ phase of migraines can often make you hungry/cause blood sugars to drop and therefore have you reaching fir something like chocolate. Then when the pain develops, the food item gets blamed, when in fact the migraine was already in progress. Always found that fascinating and tend to agree with the benefit of hindsight.
