Almost a year ago, as I was hurtling around various bits of North Africa, braving freezing night temperatures (whose idea was a trip to the Sahara in winter? Whose? WHOSE? Oh wait. Probably mine. Damn.) and a dangerous scarcity of alcholic beverages, I very nearly succumbed to a serious and potentially expensive addictive habit.
Okay, it has a funny side - but seriously it took me two and a half weeks of bleeding, sore lips before I could kick the addiction!
