Way to (Mis)-Point the Finger

So it is reasonably well heard that the tryptophan in the turkey sends the thanksgiving eater into a bit of a napping mood. Ha! it appears that it doesn't =). Ya the tryptophan can make you sleepy, but this author conjectures that it isn't the source of the whole sleepiness.
Oh ya, don't forget to get the chemical free turkey or chicken or whatever, then you won't have to worry about this whole tryptophan thing ahahahhahaha!!!!
