We all have our vices and habits (well, almost all of us), and mine is a certain fondness for original lucozade and sleeping till noon whenever possible. (I'm also a night owl, my mind works best from 8pm to 2am.) I'm slightly astounded that this hasn't come up as a thread before, to the point where I don't quite trust the search button, but still, what's your addiction? It could be a substance, an activity, or even an odd habit such as scratching your head whenever you're thinking comic style. (I do that one.)
