I’ve taken a fruity drink with melatonin about an hour ago, but I cannot sleep anyway. Why is it so? How long does it usually take for you?
The first question is whether you have already been taking melatonin for some time. If yes, the bad news is that it stops working if you take it for a few days in a row. This supplement is not harmless and it is not meant for curing general insomnia. Synthetic melatonin may work if you need to reset your biological clock, caused by a jet lag, for example. Or, if you have to sleep at daytime due to unusual working schedule. Despite its popularity, melatonin is not a universal cure and it should not be taken on a regular basis.
The Harvard medical school conducted a study in which they proved that taking melatonin is effective only if your body is not producing its own melatonin at the moment. In other words, if you take it before daytime sleep, it is effective. However, there’s no use taking it at night, when it’s dark and your own body melatonin would work better. If you still have a hard time falling asleep, it’s possible that you need to do something about your sleep hygiene.
