I'm with Yvonne in Dallas.  I have this problem sometimes, too, along with distorted taste. I will sometimes think something tastes awful while everyone else thinks the food we're eating is fine.  I do all the cooking in my house and am careful because of allergies and because we want to eat healthy.   I do pray about this, rebuke any spirits of confusion or destruction or whatever I discern may be going on.  We are spiritual as well as physical beings.  :)   Also, regardless of from where the problem stems, try EFT-emotional freedom technique.  You can look it up online.  It is like accupuncture without needles; tapping on meridians of the body to induce wellness.  You may find the problem never returns once you try it.   Blessings, Marci
