Insomnia
"Melatonin has kept all of my Tardive syndrome symptoms at bay since the first time I took 3mg of Melatonin for sleep interruptions. I was nicely surprised when I awoke that first morning: my involuntary movements of my jaw, the earaches inside and outside my ears, and the shakiness of my hands (which resulted in very scrawly handwriting)....all had disappeared! The odd time I feel my jaw move just a little and then I take 1/2 tablet of Melatonin. It keeps that symtom and others at bay."
