Without reading the story - taking a sleeping pill on a flight is VERY stupid. If there is an emergency, you might not wake up, or when you do, be unable to properly understand instructions or follow them.
If you are travelling alone, it is VERY, VERY stupid.
Since pax have learnt to think of an airplane ride as 'easy' and 'every day', some pax will do this kind of thing. That does not excuse whatever happened but someone has to tell pax not to do stupid things. Which is a task that will take until the ends of time...
