It’s 6 hours, i.e if your admission time is 7.30am no food after 1.30am (though they do say midnight as better safe… don’t wanna be puking as they put the pipe down your throat do you!), if your admission time is 12 lunchtime, they suggest you get up and have a light breakfast just before 6am, 1pm admission time is out of the ordinary, but i guess you should just have something to eat before 7am, and a bit of water. xx
