I tried over the counter Melatonin and had the worse nightmare ever! I gave the pills to someone who thought they worked perfectly.
But a couple years ago I tried to teach myself to knit, making a scarf. I was almost to the end but didn't know how to bind off. I read a little and went to bed. But I kept waking up thinking about how to bind off. Finally I got out of bed and got on the computer and found out how to bind off.
And then fell right to sleep!!!
