A member asked:

Does melatonin work immediately, or does it take days/weeks before one can experience the possible benefits?

4 doctors weighed in across 2 answers

IT MAY TAKE A FEW: Days depending on whether you have been on anti insomnics or not before. Here's a tip; take it 1-2 hours before your sleeptime. Start with 3 mgs, 2-3 days. Increase to 6 mgs if no help , for 2-3 days. Do not take more than 9-10 mgs. Be patient...

Melatonin: Depending on dose, usually effects are noted in few days, mainly helping to dose off but not maintaining sleep.
