My worst Tube sleeping episode was when I fell asleep on the Piccadilly line and ended up at one of the Heathrow Terminals. I then fell asleep on the way back, missed my stop by about four stops. Went back on the line and it was all I could do to keep myself awake to change lines at Turnham Green. I had visions of being on that Heathrow loop for the whole evening.
Perhaps the makers of these energy pills should sponsor the "Wake me up at" stickers & badges, I blogged about last week. It could be the perfect match. They could print "I wouldn't need these if I'd taken blah, blah, blah" on the bottom
