I thought of you yesterday as well. I was doing some reading/research about L-tryptophan, and came across this...

Tryptophan taken orally can convert into serotonin and melatonin
Tryptophan was given to a group of rats at 8 am in the morning, and to another group of rats at 8 PM at night. Four hours after administration, researchers measured the blood and brain fluid levels of serotonin and melatonin. During daytime administration, tryptophan raised the levels of serotonin. Interestingly, when tryptophan was given at night, serotonin levels did not increase, but melatonin levels increased significantly. Therefore, the serotonin that was generated by tryptophan administration was being converted into melatonin.

And FWIW... the reason I thought of you was the melatonin/sleep thing—not the rats.
