I'm with Tarten I can't stand my food toughing, for the same reasons.
i have to eat savory to sweet. like if we go to ihop, the eggs and bacon first the French toast or pancakes last.
Sometimes, ill eat all of one food first, beans first, potato next meat last. (My stomach is paralyzed, have to take food to digest, and meat takes about 2 days, so i eat in easily digestible order)
