I haven't done the 40hr famine since I was a teenager and it was actually a lot of fun, we had a big sleepover at a friends a couple of girls got the dizzy spells and had to end teh famine and all the other girls had the barley sugar but I felt this was cheating so I didn't. My friends parents cooked up a huge feast for us after the famine but after not eating for that long we all found it hard to eat much at all.
Anyway good on you and good luck!
