In 2003 I did the first elimination diet where I had food reactions.

About 1-2 hours after eating a heavy, groggy stupor would come over me. A little like being very drunk, I guess, with no element of exhilaration. Maybe like being very drunk AND hung-over. I would often just go lie down. Later, I would stumble and drop things.

Over the next few days my mind would slowly clear.

Along with the groggy stupor, I was tense, paranoid, and anxious, prone to rages. My back and neck muscles were painfully tight. The day after eating the food my knees and elbows hurt.
