Just want to point out that the abundance of "tryptophan makes you drowsy" stories on the news over the last couple of days are incorrect. Turkey does not contain a significant amount of tryptophan relative to other poultry (there is about the same amount of tryptophan in chicken, for example), and turkey has similar amounts of tryptophan to cheddar cheese, salmon, pork chops, beef, and lamb. If you eat a large amount of any of these products over dinner you'll feel as drowsy as would after eating a turkey dinner.
Instead of the turkey causing post-Thanksgiving-feast drowsiness, scientists (such as myself) believe it is caused by the large amount of carbohydrates ingested. Carbs release insulin, which in turn results in the production of sleep-inducing melatonin and seratonin in the brain. Ever wonder why you feel drowsy after the Christmas feast, even though you ate ham or chicken? It's not the tryptophan, it's the carbs. It's also why Dr. Atkins was so goddamn active and was able to mass-market his diet - he never slept. All of my research was done here, so I may be absolutely wrong.
