When I worked long haul red eye South America flights, the passengers usually take a sleeping pill. Except this one man took an Ambien and proceeded to drink (we didn’t know about the Ambien).

I’m sitting by the galley reading a book, it’s about 3 am. And suddenly this man comes stumbling up, absolutely naked, and attempts to relieve himself in the galley. I had to grab him by the shoulders and direct him into the lavatory, then go find his clothes and whoever he was traveling with.
