I have, made a late night flight home from CA to NC go quickly but there were moments when I just wanted to relax. I tend to get very hyped up before getting on a plane. Once we take off that adrenaline goes away and I get tired. Plus I've usually had a drink or two before flying so that kicks in. A 20 minute nap usually keeps me up the rest of the flight.
People generally avoid talking to me. I'm that one you don't really want to sit by on planes so the most interaction I have is the eye contact and the worried look on their faces that the seat next to me is theirs.
