I used melatonin for awhile when I was working in a travel oriented job. My wife used it also. We both had the same experiences,.....dreams in color and some other forms of sleep disturbance. I cant be sure but I think that after its initial release its popularity dropped off substantially . Restavit seems to work very well, but I am getting older now and don't need the sleep hours I once did. The most effective drug whilst travelling when you really need a good nights sleep but are unlikely to get it, is Stillnox. It works very well for my wife and I.
