Toxic apple turnovers

About a week ago, I ate four apple turnovers in two days. I usually never eat any Sugar or bread, and I am not sure whether it wad the Sugar or bread that is causing now frequent sneezing and blowing nose. I woke up an hour and half ago and have blown my nose thirty times. I am just plain tired. My dad bought apple turnovers because it was Thanksgiving. I regret so much eating them.:'( Maybe fasting is the only way to cure it. Well, I have learned my huge lesson here and will never eat flour or Sugar ever again. :'(
