A few years back, my dad encountered a mystery in his home.
He lived alone in a condo, on the 13th floor, in downtown Austin.
And every morning, he woke up to find that someone had eaten his cereal.
He would find a bowl sitting on the counter,
and there would be an empty cereal box and a carton of milk next to it.
He was baffled, but totally convinced someone was breaking in to eat his cereal every night.
The voice of reason said NO, this can't be so. It doesn't make sense.
And then we realized, he was on the sleeping pill Ambien...
which causes people to sometimes sleep walk.
and sleep drive.
and sleep eat.
"nocturnal eating may be a side effect of the popular sleep medication, Ambien."
So, he solved his mystery.
He was his own culprit.
And he stopped taking Ambien.
