To: Pat I can't promise you sleep with melatonin. If it was fool proof, somebody would complain anyway. In a study performed on students at either Harvard or MIT, melaetonin was used in a double blind, placebo controlled experiment to see if it helped students fall asleep faster. I do not remember all the details, but I recall something like the average time to fall asleep without melatonin was around 26 minutes and with melatonin it was around 5 minutes. I was taking 10 mg of Elavil before bedtime. This was causing problems as my body was up and walking around but my mind was still in never-never land. If I tried 25 mg, I was lucky to remember seeing daylight. This was terrible. With melatonin there is no morning after. What normally happens is I will ta ke Melatona (3 x 3mg) sit in a big chair to watch a little more TV. Something awakens me, and looking around I see it is 3:00 AM. Like I say, it works for me.
