I usually fast for 12 hours, but I overheard one of the receptionists say something about 14 hours the other day.
It's not too difficult, really - just ask for a 09:00 appointment, or earlier. That means only water after 19:00 - I don't often eat between 7pm and breakfast. What I do miss is my first-thing coffee :shock: - I've been known to take a flask with me :lol:
