What is the most effective sleeping pill out there?

I am sleeping about three hours a night; I don’t dare drive anywhere. The doctor prescribed Restoril (Temazepam) and it did nothing but make me feel weird. This is what happened to my grandson with the same drug. I don’t want to get into a regular get dressed and drive up there to be questioned routine. What is the best relaxant? I’m talking PILLS here; not hot milk. Over the counter answers are welcomed.
