 If the participants do not adhere to the meal and beverages set out in the study protocol then this can be documented using the SymTrack. To assess compliance, the participant will respond to the questions did the patient consume the study meal?, did the patient take additional food?, did the patient consume the study beverage?, and did the patient take additional alcoholic drinks?. Failure to comply with study procedures will not preclude the individual from participating on the following days.
