It was eating wheat for me as well. Once I started eating according to the ketogenic diet, I no longer needed naps during the day.

I'm another one of these: stopped eating wheat, immediately needed less sleep. Does anyone know of any research on this phenomenon? There are obviously lots of anecdotes, but I can't find any studies.

  Research on this very subject was cited on a Norwegian show called Pulse, but it's too long since I saw it that I'd be able to find it again. There apparently is a correlation between wheat and sleepiness, for some.
