Hi, Your history is suggestive of seizure phenomenon(Fits). Food and alcohol can trigger seizure. You need to consult Neurologist and get evaluated clinically and needs EEG and, MRI brain along with routine biochemical testing for further confirmation and management of same. Any food can be a culprit, although wheat, soy, sugar, dairy and at times others are the most common.  Less commonly, food chemicals such as MSG or aspartame may contribute to seizures in some cases.  The latter are called excitotoxins because they irritate the nervous system.  Eliminating food chemicals, sugar and wheat will help some people who suffer from seizures
