Imagine that the typical workweek has just started. Monday arrives and you have to carve a path through hell itself. Once you have successfully beaten back the weekday blues, things seem marginally better. By Wednesday, you are almost in control and end up having the most productive workday of the week. It could be that it took you three days to acclimatize yourself to getting back to work. Or, it could be something you ate! Think back of your amazing days at work and then link them to what you had for lunch on those days.
