Amitriptyline
"I have been taking 25 mg Amitriptyline for several years almost every night and really couldn't be more pleased and grateful. I call it my miracle cure for insomnia, as long as it's taken at the right time (9 pm). Too late in the evening it doesn't work very well. My initial dose of 50 mg caused too much postural syncope (dizziness upon standing). If I need to boost it, I can take 1mg melatonin, but I will have a later time to rise and a bit of a hangover. I initially took this drug for chronic dyspepsia and I suspect that routine use is keeping that at bay."
