After eating what you ate, that seems like a lot of stuff that could of caused a reaction. Rice, bread, and even the turkey.
You should be introducing things back one at a time and not 3 or 4 in one meal cause it becomes a lot harder to determine what gave you the reaction.
Did the turkey have antibiotics in it like most of them do? Did the Rice or bread cause a reaction which is very possible?
Unfortunately taking a bunch of antifungals with food you really want to eat isn’t going to counteract any negatives of the food. It’ll just cause a war in your stomach which could also account for your nausea.
