Have fallen asleep on the train almost every day since i started working (about 4 years ago). nothing wrong with it, i missed by stop only twice...once when abosultely plastered after the christmas lunch
I physically can't. I'm a very fussy sleeper, and unless I'm horizontal and cool then sleep's a no-no. Can't even sleep on the couch at home, has to be a wide, flat space. Plus I wear contact lenses so can't really sleep through the day anyway.
