After how many days does melatonin start working?
For me it never did. But I whole heartedly wish it does for you!
Last time i was in the hospital they gave me melatonin at night but it never seemed to make me sleepy.
It worked for me from the first night I took it and continues to work very well.
About 30 minutes.
It takes three hours for melatonin to work. I have to take it three hours before going to bed and it works for me most of the time.
Well it did not work for me either. But my pdoc said wait for few days for it to start working.
