What you describes seems to me to be a typical placebo effect !!! I am 
currently completing my PhD on the effect of melatonin on reproduction. I 
known this hormone very well, and I can say that melatonin is a hypnotic 
hormone...I mean melatonin induces spleep!!! and  also decreases the 
arousal level of vigilance. I just can understand how it could help you to 
releive sleepiness!
What sort of melatonin capsules do you take? I mean in the 
US, most capsules in supermarkets or health food stores does not contain any 
melatonin...Be very careful with the melatonin sold in the US, 
because no FDA control is required for the "melatonin" synthesis that they 
contain. They may contain many other products...
