[This is a true story.]
My grandfather lived in a small town. He used to go to the theater every weekend.
In those years there was a dictatorship in Spain and theaters ran a regime propaganda documentary before movies started called NO-DO. My grandfather was concerned that he couldn't make it to the movie, he fell asleep watching NO-DO and that was it.
So, he visited very worried Doctor Valentín, who was the town's local doctor. He explained to him he couldn't pass the NO-DO and there was no way for him not to fall asleep. The doctor said: "Joaquín, do you know how many people come here to get sleeping pills? If you are sleepy, sleep!"
He left the doctor relieved, and just slept.
