I have a chronic sleep disorder and they prescribed me this in the form of circadin. I think it does have an effect, sure, but it's a mild one. I take it in conjunction with benzos for any real effect.
I think it may depend on the cause of the sleeping issue, what exactly it is, and the severity of the problem. Nothing really works on me and sleep, but it may be helpful for others!
Also to the above - all those "natural" remedies only usually work on those with very mild sleep issues, or problems that are the results of psychosomatic causes. They will have no effect on chronic entrenched sleeping disorders.
I have been awake for days at a time and started to hallucinate before, and people will tell me to just drink chamomile tea and it will cure it. Nope.
