Beer cans
Maybe once in about 2 years I travel on a long haul flight and do'nt really get much sleep in a seated position and legs too start getting restless. Life does get better after a few beers. But after the first can, I am hesitant to ask. After some dilemma, one more (though I would'nt mind another 2). So, how far can I push my luck? 4 OK?
