Lori asked me to look into this right before I moved.
The Wakeup Diet for narcolepsy.
As far as I can tell it's a manic collection of correlations and assumptions.
No physiological explanations. No mention of orexin. No scientific citations.
And the author does not identify him/herself, either.
That's enough reason to ignore it.
But the suggestion that we should avoid coffee only proves this person has no idea what the hell they are talking about.
Hope that helps... sorry it took so long.
