A brief cold shower with water pouring down onto your skull will nudge your body temperature down a bit, which signals your body it's time to sleep. You can also try cycling diphenhydramine 40-100 mg, melatonin 0.5 - 1.5 mg, and orange blossom water, never taking any one more than two nights in succession.

Orange blossom water, which you can find in Arabic grocery stores, is used to flavor deserts, and is traditionally used in some Mediterranean countries as a relaxing tea ("cafe blanc": "white coffee" though it's actually colorless), and, in a dose of a drop or two added to a milk bottle, to help children fall sleep. Drink two or three tablespoons of orange blossom water in a cup of warm water and you will soon feel a heavy shroud of sleepiness descending upon you. You'd better be near your bed when you finish that cup. The effect seems to work no more than twenty minutes or less, so it's perfect to help you fall asleep, without the risk of having to fight off a drugged feeling hours later should you have to get up and be alert.
