Does Milk Make You Sleepy?

A lot of people drink a glass of milk before bed because it supposedly helps them sleep. But milk's sleep-inducing effect may be mostly in your head. Although milk contains both tryptophan and calcium, two compounds that reportedly induce drowsiness, a glass of milk doesn't really have enough of either to have a noticeable effect.

If you're after a good night's sleep, I'd keep it to just one glass. Drinking too many fluids right before bed may cause your bladder to wake you in the middle of the night.
