I was amazed to read this article that tells of patients in brain damage states who experienced miracle recoveries or remissions after they were given a sleeping pill; and it turns out to be the same sleeping pill that I take 2 or 3 nights a week if I can't sleep. Wow.
Years ago, I remember taking a different sleeping pill and once I mistook the tablet for a vitamin pill and took it in the afternoon. After I realised my mistake, I didn't feel sleepy which surprised me.
I'd love to see a TV documentary about this. The tablet helps an estimated 60% of cases so far. I'm happy for the people who get to see their loved-ones wake up.
