The field of medicine has always been dynamic. Healthcare is a 24/7 functional department and doctors are always on their toes in the hospital.Demanding working hours, especially night shifts require more alertness and most doctors resort to caffeine to keep them awake. In the hospital, residents and interns make up the strong-ground while students slog into the night hours with the help of caffeine. Though caffeine is not classified as harmful, anything in excess has deleterious effects. Thus it becomes important to keep in check of the caffeine consumption of medical students, interns and residents.
