For example, Katie bought some lunchmeat at the store recently just to give us a little lunch time variety. When she bought it, she told me what it was but that completely slipped my mind. 

Then one day I was craving a turkey sandwich, so I grabbed some of the lunchmeat and made one.

I didn't know if it was because I hadn't eaten turkey in such a long time, but this stuff just tasted off. Not rotten or expired or the like, just not turkey.

When Katie got home, I asked her what she thought of her sandwich as I had made her the same thing. She said it was fine. 

I was confused.

A couple days later, I went in for a second shot. This was when I noticed the label on the packaging... chicken breast.

Then I tasted it and any sour feeling my taste buds and brain had toward it were gone. It was... chicken breast. Plain and simple and perfect.

I went from thinking I was going to be sick to having no problem eating it whatsoever.

I know the brain is wired to do some pretty gnarly stuff, but that just seems a bit over the top to me.
